If a citizen of China is naturalized in another country, but the immigrant does not move, does he still need a Chinese visa to live in China?

You really have no idea. That's what immigration means. Immigrants can survive. Otherwise, you are an illegal immigrant and will be arrested and deported. Generally speaking, only those who meet the immigration conditions are eligible to apply for immigration, not everyone can. Immigration is to obtain permanent residency in the country, just like the American green card. Only people with permanent residency are eligible to apply for naturalization, which is a basic condition for naturalization, but it does not mean that they can acquire the nationality of the country with permanent residency, and naturalization will be restricted by other conditions. Generally speaking, naturalization is not that easy. If you have entered a foreign country, but you haven't taken your Chinese ID card to the police station for cancellation, then your Chinese ID card can still be used, and it is as valid as in China or other countries, because the United States, Canada and European countries allow dual citizenship, and the Chinese ID card is still valid there. Although China does not recognize dual nationality, the information of China people's foreign nationality cannot be obtained and identified by the domestic household registration administration. Moreover, the cancellation of the certificate needs to be handled by myself to be effective. If it is not cancelled, the certificate is still valid in China. So if you live in China, you don't need a visa, just use China's certificate.
