# Multidimensional collaboration and strict regulation to strengthen the defense line for fair trading in the capital market

This year's "No. 1 penalty" issued by the China Securities Regulatory Commission directly targets market manipulation, with individual Yu Han being fined over 1 billion yuan for manipulating the stock price of "Doctor Glasses"; the Zhejiang Securities Regulatory Bureau has launched an investigation into misleading statements in the restructuring plan of Sunflower; the Shenzhen Stock Exchange is closely monitoring \*ST CDT and \*ST Changyao Group, which have been filed by the CSRC for suspected false financial data... Recently, a series of regulatory cases have been intensively announced, demonstrating the regulatory authorities' resolute attitude of "zero tolerance" towards market violations, and conveying a clear signal to strengthen trading supervision, maintain market fairness, and prevent large fluctuations. From administrative penalties to criminal accountability, from precise strikes to platform co-governance, regulatory authorities are building a multi-dimensional and three-dimensional regulatory network, striving to create a long-term governance pattern of "dare not violate, cannot violate, do not want to violate," and promoting the continuous purification of the market ecology through the enhancement of regulatory effectiveness.
