How can a person who has not changed his nationality after emigration apply for an ID card when he returns to China without a household registration book?

According to the new immigration control measures, China citizens living in the host country can apply to the local embassy abroad before entering the country, and they can use passports instead of ID cards after returning home. No longer do not issue ID cards.

If you want to apply for an ID card, that means you must apply for permanent residence. China does not recognize dual citizenship. You have to go abroad or have a China hukou.
