There are two periods of validity on visas issued by Chinese embassies and consulates abroad: one for entry, valid up to a particular year, month, day, and another for permitted stay, indicating the permitted period of stay in China. The holder of the visa may enter and exit China once or multiple times during the entry validity period, and following entry, the holder may remain in China for the number of days indicated on the visa. Entry and exit dates for foreign nationals are generally determined in accordance with the dates stamped on the passport during inspection at the border.
