Can I buy listed companies through the secondary market? To what extent, it is best to give an example, thank you.

Of course. According to the relevant laws, when you buy the tradable shares of a listed company through the secondary market, you should report to the Shanghai Stock Exchange when its shareholding reaches 2.5% (I am not familiar with the reporting matters), and report to the Shanghai Stock Exchange when its shareholding reaches 5%. This is done level by level. When you reach a certain shareholding and have the right to vote and make decisions on the production and operation of listed companies, you will become the largest shareholder and realize the acquisition of listed companies. Of course, if you want to buy a listed company, you need to know the number, background and strength of the first (second) largest shareholder of the listed company, and make careful arrangements and feasible plans. In order to hide their whereabouts, it is necessary to have multiple accounts to buy chips in the secondary market, and the number of shares held by each account cannot exceed 2.5% (circulation disk), so that the original first (second) largest shareholder can not change, which is the key.
