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. 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. 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 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. 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.
During Later Tang Later in 923, Later Liang was conquered by its rival
Later Tang. 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 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. 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. However, by 929, the relationship between Qian Liu and the Later Tang imperial government had been damaged because Emperor Mingzong's chief advisor
An Chonghui considered Qian Liu to be arrogant and rude in his letters to An. At An's request (after An accused Qian Liu of spying on the matters of the Later Tang imperial court), Emperor Mingzong issued an edict ordering Qian Liu to retire with the title of
Taishi and stripping him of all his other titles (including, presumably, King of Wuyue), and further put all Wuyue emissaries to the Later Tang court under arrest. Qian Liu had Qian Chuanguan submit a petition on his behalf claiming innocence, but An (and Emperor Mingzong) ignored Qian Chuanguan's petition. (The Wuyue emissaries were released in 930 after Qian Liu submitted another petition through Pei Yu (裴羽), the Later Tang emissary to Wuyue's southern neighbor
Min and this time apologized for his own faults, but the full relations were not reestablished until 931 after Emperor Mingzong forced An into retirement (and, after blaming An for the Later Tang imperial government's confrontations with Qian Liu,
Meng Zhixiang the military governor of Xichuan Circuit (西川, headquartered in modern
Chengdu,
Sichuan), and
Dong Zhang the military governor of Dongchuan Circuit (東川, headquartered in modern
Mianyang,
Sichuan), killing An), at which time Emperor Mingzong restored all of Qian Liu's titles. In May 932, Qian Liu fell deathly ill, and he, to see whether his subordinates were in fact faithful, asked whom they would support as their new leader — at which time the generals and officials all endorsed Qian Chuanguan. Qian Liu thus entrusted the seals and the keys to the treasuries to Qian Chuanguan, left directions that he should serve whichever dynasty controlled the
Central Plains with care even if the dynasty changed, and then died. == Reign ==
