According to Baidu law, the CSRC, as the regulator of the securities market, has the power to investigate and enforce the law. If there are illegal acts of securities firms, the CSRC can investigate and take corresponding regulatory measures. When conducting an investigation, the CSRC can obtain evidence related to illegal acts, including financial information such as bank running water. Therefore, the Securities Regulatory Bureau can collect the bank's running water and investigate whether the brokers have violated the law.
However, when conducting an investigation, the CSRC also needs to abide by relevant laws, regulations and procedures to ensure the legality and fairness of the investigation.
