Do listed companies have to publish quarterly reports?

Listed companies don't have a monthly report, and they can tell you the sales situation of the month at most. Quarterly reports are generally published within 1 month after the end of a quarter, semi-annual reports within 2 months and annual reports within 4 months. If the release time of each company is uncertain, it shall be decided by the listed company. You can download the quarterly report on the website of listed companies or the website of China Securities Association. Personally, I think it is more convenient to download on the website of China Securities Association!
