My husband is Filipino. We got married, but the number of entry times was not given on the visa. He is going back to China this time and doesn't know how to apply for a visa.

Under normal circumstances, visas issued by the embassy will indicate the number of entry times in Arabic numerals, or directly indicate MULTI to indicate that most of them can enter the country. If you need to apply for a visa again, you can bring a marriage certificate with you when submitting the materials, and you can apply for a visit visa more than once a year. Very convenient. Good luck.
