Does renunciation of nationality mean renunciation of household registration or renunciation of nationality?

Does renunciation of nationality mean renunciation of household registration or renunciation of nationality:

Resignation of nationality is not a simple cancellation of account, but a process of applying for renunciation of nationality. For example, in the United States, local immigration officials must check their documents. If they have China passports, they are from China, and if they have American passports (born in China), they are Americans.

To withdraw from China nationality, you should apply to the Exit-Entry Administration of Public Security in prefecture-level cities to fill in the fee of 200 yuan. The prerequisite for withdrawing from China nationality is to cancel the account. According to the Law of China on the Administration of Exit and Entry of Citizens, those who leave the country temporarily also need to cancel their accounts. In fact, the cancellation of household registration is only a measure of household registration management, not nationality management.
