Overseas, it is a fixed match.

The usage of foreign is 1:foreign basically means "going abroad, being abroad", that is, someone goes to or is in another country (one or several countries), which can mean traveling or doing business abroad, or living or working abroad. In formal style, foreign countries can also mean "spread everywhere, spread widely, spread everywhere and be widely known". In spoken language, foreign countries can also mean "inexplicable, not at all" to explain that "outdoor, outdoor" is an archaic usage.

Usage 6: the spelling and pronunciation of 6:outside and above are similar, but their meanings are different. Be careful not to confuse them.
