Both Macau and Hong Kong Immigration provide duplicate card where the first page is for arrival and the second is for the departure. Make sure you sign on both forms upon arrival and retain the second card in your passport, because if you lose the second or the departure card, you will not be allowed to leave Macau or Hong Kong. Macau Immigration Arrival/Departure Card is written in Chinese, Portuguese and English, while Hong and China are written in Chinese and English.

China arrival card is detachable with the departure card. Visitor can only fill the arrival card which will be given to the immigration officer at the arrival counter. You don't have to retain the departure card in your passport.
