If a mainland resident marries, both parties need to go to the marriage registration office in the place where one party's permanent residence is located to register the marriage.
If a Chinese citizen marries a foreigner in the mainland of China, or a mainland resident marries a Hong Kong resident, a Macao resident, a Taiwan resident, or an overseas Chinese in the mainland of China, both parties need to jointly go to the marriage registration authority in the place where the mainland resident's permanent residence is located to register their marriage.
