The money at that time was the time when Zhu Wen, Li Keyong and Li, the father and son of the Back Beam, competed for hegemony. Shi Jingtang saved Li Siyuan from danger several times and became Li Siyuan's confidant. In the fourth year of Tongguang in the later Tang Dynasty (926), Li, Li and Li were killed by rebels, and Li Siyuan proclaimed himself emperor in Luoyang, the later Tang Dynasty. After Li Siyuan's death, Li Conghou succeeded to the throne as Emperor Min of the later Tang Dynasty. At that time, Fengxiang, Li Congke, Hedong and Shi Jingtang all paid tribute to their troops. Soon, Li Congke killed the late Tang Emperor Min, changed his name to "Qingtai" and established himself as the emperor, that is, the late Tang Emperor. Shi Jingtang accused the late Tang emperor of being his adopted son and asked him to give way to Li (his fourth son). At the end of the late Tang Dynasty, the emperor tore up his watch and cut his rank, taking our special envoy Zhang Jingda as the omnipotent ambassador of Taiyuan, and 30,000 soldiers besieged Taiyuan.

While the imperial court was engaged in rebellion, Shi Jingtang turned to the Khitan for help: Please be a vassal and serve the Khitan with your father. After his appointment, he will cut Lulong and the states north of Yanmenguan and Qidan, and promised to give Qidan 300,000 silks every year. Yelvdeguang, the Khitan general, was overjoyed and led troops to defeat Zhang Jingda. In November of the third year of Qing Dynasty in the late Tang Dynasty (936), Shi Jingtang was named Daikin Emperor in the main book of Qidan, and was renamed Tianfu in the Yuan Dynasty with the title of Jin. Shi Jingtang is located in Liulin (now southeast of Taiyuan City, Shanxi Province). In the same month, Shi Jingtang invaded Luoyang and died in the later Tang Dynasty. In the second year of Tianfu (937), Jin moved the capital to Bianliang.

There are historical records on the issue of coinage during the "Tianfu" period in the late Jin Dynasty. "History of the Old Five Dynasties" contains: In November of the third year of Tianfu, he was ordered to "privately make money in the world, taking' Tianfu Yuanbao' as the text". Song Hongzun's "Quan Zhi" quoted Bai Songxu as saying: In November of the third year of Jin Tianfu, he ordered that "the capital of the three cities, Yedu and Zhudao, regardless of public or private interests, promised to make money if they deserved copper. Still with' Tianfu Yuanbao' as the text, read it in Zuo Zhuan. Entrust the salt and iron envoy to cast samples and teach the way, so that each money weighs two baht and four tired, and ten money is one or two. "

There are many versions of "Tianfu Yuanbao" now, which are large, medium and small in size, light in diameter and many characters, and should be privately cast. However, the author believes that the above records only illustrate the situation that Xu Min privately minted coins in Tianfu for three years, which does not mean that coins of other specifications have not been minted before, nor does it mean that coins of other specifications have not been minted in the later Jin Dynasty. On the contrary, the sentence "Tianfu Yuanbao is still writing, and it is read by Zuo Huan" just tells the truth that coins with Tianfu Yuanbao as the text have been forged before. In the Five Dynasties, it was decided to change the dynasty and make money. "Kaiping" and "Tongguang" in the previous dynasties were all coins, and they all made a lot of money. Although Shi Jingtang kowtows to the outside world, he will not be worse than others at home. Therefore, the author believes that at the beginning of the founding of the late Jin Dynasty, not only coins were minted, but also large amounts of money should be minted.
