There are three traders in Yi'an Technology: Li Biao, Tang X and Luo Jianzi. During the trading process, Li Biao used the limit-down method to attract funds. Later, due to various reasons, Li Biao and Tang X left the company midway shortly after completing the fundraising. After that, after the funds for Yi'an Technology's hype were in place, it began to skyrocket. The main trader at this stage was Luo Jianzi, who remained among the three people at the beginning. Until the collapse, he was investigated and arrested by the China Securities Regulatory Commission. Li Biao and Tang X escaped because they left early.

Since Master Tang’s operation method is very similar to the original method of Yi’an Technology, and he is also known as: Muzi, it is basically believed that Master Tang is Li Biao of Yi’an Technology back then.
