Can I keep my China nationality after marrying a Korean?

Nationality does not change automatically. If you want to change your nationality, you must apply for China nationality. If you want to live permanently in a foreign country, you must get a green card of that country, otherwise you will not be allowed to live permanently in a foreign country. As for restrictions, depending on the relevant regulations of that country, there are definitely restrictions. From 201110, South Korea will implement the system of allowing dual nationality, that is, if the parties swear not to exercise foreign nationality in South Korea, they can maintain their foreign nationality while retaining their Korean nationality. South Korean Prime Minister Zheng Yuncan presided over the State Council in the central building of Sejong-do Government on the 27th, and deliberated and voted on the amendment to the nationality law containing the above contents. The Amendment to the Nationality Law stipulates that you can have dual nationality at the same time before the age of 20, but within two years from the age of 20 to 22, if you decide to choose Korean nationality and swear not to exercise foreign nationality in Korea, you can keep dual nationality. At present, it is stipulated that Korean nationality will be automatically lost if you do not choose nationality within the specified time. Foreign-born people want to acquire Korean nationality, and only by giving up foreign nationality can they acquire Korean nationality. In addition, if the amendment is used to avoid services, the benefits of this policy cannot be obtained. The amendment also stipulates that marriage immigrants, special naturalized persons, outstanding foreign talents, overseas adopters, etc. If they swear not to exercise foreign nationality in Korea, they will not lose Korean nationality. The naturalization of outstanding foreign talents is not subject to the time limit for staying in Korea. At the same time, starting from next year, when confirming the family relationship with foreigners' families such as partners or children, foreigners' identity card numbers can be recorded in the family relationship register, and this legal amendment related to family relationship registration has also been passed.
