Qian Yuanguan () (30 November 887 – 17 September 941Zizhi Tongjian, vol. 282.), born Qian Chuanguan (錢傳瓘), also known by his temple name as the King Shizong of Wuyue (吳越世宗), courtesy name Mingbao (明寶), was the second king of Wuyue during the Five Dynasties and Ten Kingdoms period of China. He ascended to the throne in 932, when his father Qian Liu (King Taizu) left the state in his hands, to 941. He was the father to all three of Wuyue's subsequent kings.

Early life Qian Chuanguan was born in 887, during the reign of Emperor Xizong of Tang, at a time when his father Qian Liu was serving as the prefect of Hang Prefecture (杭州, in modern Hangzhou, Zhejiang), loosely as a vassal of the warlord Dong Chang the military governor (Jiedushi) of Weisheng Circuit (威勝, headquartered in modern Shaoxing, Zhejiang).Zizhi Tongjian, vol. 256. He was Qian Liu's seventh son, and his mother was Qian Liu's concubine Lady Chen.

The first significant reference to Qian Chuanguan, historically, was in 902, when his father Qian Liu, then the military governor of both Zhendong (鎮東, i.e., Weisheng, now named Zhendong) and Zhenhai (鎮海, headquartered at Hang Prefecture) Circuits, was facing a major threat to his control of the region in the forms of a mutiny led by the officers Xu Wan (徐綰) and Xu Zaisi (許再思), who were able to obtain the aid of Tian Jun the military governor of Ningguo Circuit (寧國, headquartered in modern Xuancheng, Anhui), a vassal of the major warlord Yang Xingmi the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu). Qian Liu was able to get Yang to exert pressure on Tian to withdraw by sending the officer Gu Quanwu (顧全武) and Qian Chuanguan's older brother Qian Chuanliao (錢傳璙) to Yang to persuade Yang that if Tian became any stronger, he would pose a future threat to Yang, and for Qian Chuanliao to subsequently remain at Huainan to serve as a hostage. (Yang subsequently gave a daughter to Qian Chuanliao in marriage.) Yang therefore warned Tian that if he did not withdraw, he would send another officer to take over the command of Ningguo from him. Tian was forced to withdraw, but extracted from Qian Liu the promise of a monetary tribute, as well as a son to serve as hostage (with Tian offering to give the son a daughter in marriage). When Qian Liu gathered his sons and asked them, "Who is willing to be a son-in-law for the Tians?" none responded initially. Qian Liu considered sending Qian Chuanguan's younger brother Qian Chuanqiu (錢傳球), but Qian Chuanqiu refused, drawing Qian Liu's great anger such that Qian Liu almost killed him — at which point Qian Chuanguan volunteered to go. Qian Liu's wife Lady Wu, who considered Qian Chuanguan like her own son as well, wept bitterly, not wanting to send him, but Qian Chuanguan responded, "In order to save the state from disaster, how can I spare my own body?" He thus left with Tian's army as Tian withdrew, and apparently married Tian's daughter.Zizhi Tongjian, vol. 263.

In 904, Tian, unhappy that Yang was continuously curbing his desire to expand, rebelled against Yang along with An Renyi (安仁義) the military prefect (團練使, Tuanlianshi) of Run Prefecture (潤州, in modern Zhenjiang, Jiangsu). Initially they caused much apprehension within Yang's realm, but Tian shortly after began to suffer repeated defeats at the hands of Yang's generals Li Shenfu and Tai Meng (臺濛). As Tian's situation became more and more desperate, and perhaps because Qian Liu sided with Yang in this war, each time he suffered a defeat, he considered killing Qian Chuanguan, but Qian Chuanguan escaped death as he was protected by Tian's mother Lady Yin and Tian's brother-in-law Guo Shicong (郭師從). After Tian was finally defeated and killed in battle by Tai, Qian Chuanguan was able to return to Hang Prefecture with Guo, and Guo thereafter became an officer under Qian Liu.Zizhi Tongjian, vol. 264.

During Qian Liu's reign

During Later Liang In 907, the major warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), who had had Emperor Xizong's brother and successor Emperor Zhaozong, and then Emperor Zhaozong's son and successor Emperor Ai, under his physical control for a number of years, had Emperor Ai yield the throne to him, ending Tang and starting a new Later Liang as its Emperor Taizu. While some independent warlords refused to recognize the new emperor, Qian Liu did so, and thereafter was created by the Later Liang emperor as the Prince of Wuyue; his state thereafter became known as Wuyue.Zizhi Tongjian, vol. 266.

Shortly before taking the title of Prince of Wuyue, Qian Liu sent Qian Chuanliao and Qian Chuanguan to attack Lu Ji (盧佶), who controlled Wen Prefecture (溫州, in modern Wenzhou, Zhejiang) and whose brother Lu Yue (盧約) controlled Chu Prefecture (處州, in modern Lishui, Zhejiang). Anticipating Qian Chuanliao and Qian Chuanguan to attack by water, Lu Ji placed his fleet at Qing'ao (青澳, in modern Taizhou, Zhejiang) to defend against their attack. Believing that the better strategy was to bypass Lu Ji's fleet, Qian Chuanguan advocated, and thereafter his army did so, advancing to Angu (安固, in modern Wenzhou), landing there, and directly attack Wen Prefecture. They were able to quickly capture Wen Prefecture and capture and kill Lu Ji. Qian Liu subsequently ordered them to advance on Chu Prefecture. Subsequently, Lu Yue surrendered Chu Prefecture to Wuyue.

In 913, Li Tao (李濤), a general of Wuyue's northern neighbor Wu (i.e., formerly Yang Xingmi's domain, now under the rule of Yang's son Yang Longyan) attacked Wuyue, going over Qianqiu Heights (千秋嶺, in modern Xuancheng) heading toward Qian Liu's hometown Yijin Base (衣錦軍, in modern Hangzhou). Qian Liu had Qian Chuanguan, who was then the prefect of Hu Prefecture (湖州, in modern Huzhou, Zhejiang) command the defense against the attack while sending Qian Chuanliao to attack Wu's Dongzhou (東洲, in modern Changzhou, Jiangsu) to try to divert Wu's forces. Qian Chuanguan cut off trees on Qianqiu Heights to cut off the path of the Wu army and then attacked it, taking Li and 3,000 Wu soldiers captive. Later in the year, the Wu officers Hua Qian (花虔) and Wo Xin (渦信) rendezvoused at Guangde (廣德, in modern Xuancheng) to plan another attack on Yijin. Qian Chuanguan took the initiative and attacked Guangde himself, capturing Hua and Wo. However, when Qian Chuanguan, Qian Chuanliao, and another brother, Qian Chuanying (錢傳瑛), then attacked Wu's Chang Prefecture (常州, in modern Changzhou) together, the Wu regent Xu Wen and the Wu general Chen You (陳祐) defeated them, killing many Wuyue soldiers.Zizhi Tongjian, vol. 268. Later in 913, then-reigning Later Liang emperor Zhu Zhen created Qian Chuanguan the Baron of Dapeng (大彭縣開國男), and in 914 upgraded the title to marquess.

In 919, at Zhu Zhen's order, Qian Liu sent Qian Chuanguan, who was then serving as his deputy military governor, to attack Wu's Dongzhou with 500 ships. The Wu general Peng Yanzhang (彭彥章) defended against the attack. In anticipation for the battle, Qian Chuanguan loaded his ships with ashes, sand, and beans. Furthermore, this battle also witnessed the world's first proper 'flamethrower' that used gunpowder after its recent invention in 850. Having been installed in Qian Chuanguan's dragon ship and decorated with silver, his weapon was readied in a way that would conceal it and hide it from the enemy in the event of his capture. When the fleets encountered each other at the Battle of Langshan Jiang, Qian Chuanguan maneuvered his fleet into an upwind position and then scattered ashes at the Wu fleet, making the Wu soldiers unable to see his ships, and then spread the decks of his own ships with sand while throwing beans at the Wu ships, causing the Wu ships' decks to be covered with beans and the Wu soldiers to thereafter slip and unable to act quickly. He then threw torches at the Wu ships, setting them afire and causing a general rout. Qian Chuanguan's makeshift double pump flamethrower also aided in tearing through the Wu's forces, delivering destruction they have never withstood before. When Peng's deputy Chen Fen (陳汾) did not come to Peng's aid, Peng committed suicide. Qian Liu then ordered Qian Chuanguan to attack Chang Prefecture, and Xu personally defended against the attack. At that time, the weather was dry, and the Wu soldiers were able to set fires against the Wuyue army, causing Wuyue soldiers to panic. The Wuyue generals He Feng (何逢) and Wu Jian (吳建) were killed, and Qian Chuanguan was forced to flee. Xu took the opportunity to negotiate peace between the two states by returning the captives that he took, and it was said that for the next 20 years, there were no major confrontations between the two states.Zizhi Tongjian, vol. 270.

In 920, Zhu Zhen bestowed on Qian Chuanguan the honorary titles of military governor of Qinghai Circuit (清海, headquartered in modern Guangzhou, Guangdong, then under the rule of Southern Han) and chancellor (同中書門下平章事, Tong Zhongshu Menxia Pingzhangshi). In 923, when Zhu Zhen created Qian Liu the King of Wuyue (國王, Guo Wang) and Qian Liu thereafter acted as full sovereign of the state, he commissioned Qian Chuanguan as the acting military governor of Zhenhai and Zhendong and put Qian Chuanguan in charge of the military affairs.Zizhi Tongjian, vol. 272.

Meanwhile, by the time that Qian Chuanguan was in his 30s, he still had not had a son with his then-wife Lady Ma. At that time, there was an order by Qian Liu in effect in the Wuyue realm that officials were not allowed to have concubines, but Lady Ma went to see Qian Liu to ask for an exemption on Qian Chuanguan's behalf. Qian Liu responded to her happily, "My family's future bloodline is in your hands." He thus allowed Qian Chuanguan to have concubines, and they bore him a large number of sons, whom Lady Ma treated as her own sons.Zizhi Tongjian, vol. 282.

During Later Tang Later in 923, Later Liang was conquered by its rival Later Tang. In 924, Qian Liu established tributary relations with Later Tang, formally submitting to Emperor Zhuangzong of Later Tang as a vassal. Emperor Zhuangzong confirmed all of the titles that Later Liang had bestowed on him.Zizhi Tongjian, vol. 273. He also confirmed Qian Chuanguan's titles of military governor of Qinghai, as well as acting military governor of Zhenhai and Zhendong, and also bestowed the greater honorary chancellor title of Zhongshu Ling (中書令, Zhongshu Ling), acting Taishi (太師), and Kaifu Yitong Sansi (開府儀同三司).

In 926, Qian Liu fell ill briefly, and went to Yijin to recuperate, leaving the affairs of the state to Qian Chuanguan, until Qian Liu completed his recovery and returned to Hang Prefecture.Zizhi Tongjian, vol. 274.

In 928, Qian Liu wanted to formally designate Qian Chuanguan his heir, but to make sure that the other sons agreed (particularly because Qian Chuanguan was not the oldest), he gathered them and stated to them, "Describe your accomplishments. I will make the one with the most accomplishments my heir." Qian Chuanguan's older brothers Qian Chuanchou (錢傳儔) and Qian Chuanliao, as well as younger brother Qian Chaunjing (錢傳璟), all praised Qian Chuanliao's accomplishments.Zizhi Tongjian, vol. 276.The description of this event, which was given in the Zizhi Tongjian, actually referred to Qian Chuanjing as an older brother, but the other sources indicate that Qian Chuanjing was younger — although he might have been considered particularly honored since, at one point, Emperor Ai apparently considered marrying a sister to him. See Spring and Autumn Annals of Ten Kingdoms, vol. 83. Qian Liu thus submitted a petition to then-reigning Emperor Mingzong of Later Tang (Emperor Zhuangzong's adoptive brother and successor) to pass the two circuits to Qian Chuanguan. Emperor Mingzong agreed and issued an edict making Qian Chuanguan the military governor of Zhenhai and Zhendong.
