According to the Shanghai Securities Report, following the bizarre removal of 1.33 billion yuan of capital from the listed company and the rapid filing of a lawsuit against the company and related officials by the China Securities Regulatory Commission, Weichuang Co., Ltd. announced on the evening of March 26 that the company had received supervisory letters from three independent directors. The reporter noticed that before, it was rare for sole directors to submit supervisory letters to listed companies. According to analysis by industry sources, this is also a major characteristic of the changes in the sole director ecology after the implementation of the new sole director regulations.
