Wu Jihan set up a small retail center in Shenzhen to take control of the chain.

According to Tianyancha data, on July 16, Beijing Siyuan Continental Technology Co., Ltd., owned by Hong Kong Bittech, established a new company in Shenzhen, Shenzhen Siji Yanghang Technology Co., Ltd., whose legal representative is Wu Jihan. On July 12, it was announced that Wu Jihan had chosen Long Zhengxiang as the new line and production manager in Shenzhen. Since Ketuan Zhan took control of the factory in Shenzhen to protect production and export, Wu Jihan wanted to regain control of the line and manufacturing and resume business and develop mining equipment. Currently, Ketuan Zhan is still trying to sell and develop his own mining equipment, but is struggling to secure his chips and finances.
