Do shareholders of domestic-funded enterprises need to change to Hong Kong-funded enterprises after they immigrate to China?

Article 57 of the Provisions of the Ministry of Commerce on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors: "Mergers and acquisitions of enterprises in other parts of China by investors from Hong Kong Special Administrative Region, Macao Special Administrative Region and Taiwan Province Province shall be handled with reference to these Provisions." Hong Kong, Macao and Taiwan are all managed according to foreign investment. Except that the nature of the enterprise indicates that overseas Chinese from Hong Kong, Macao and Taiwan are not foreign investment, everything else is the same, so there is no need to be too rigid about nationality. Just look at it according to the customs area.
