the period of stay of foreigners in China can be automatically extended for two months. No extension application is required during the extension period. Expats can still stay in China legally or leave the country normally.
Also, foreigners needing to come to China urgently who did not get the time to apply for a visa before arriving will be allowed to apply for a visa upon arrival into China. Assuming that they have the relevant invitation letters.
