Chinese passport
Two-way Permits are issued, just like the Chinese passport, by local Exit and Entry Administrations (EEA) of local Public Security Bureaus (PSB) of their places of residence. Mainland residents must apply for a new permit in person, while exit endorsements can be obtained either through the automatic endorsement machine located in EEA offices or by mail for persons residing in Guangdong. Exit endorsements are not issued to a permit with a remaining validity of less than three months.
