You should send a message to BG support with this question. They might have a work-around for such a situation.
China is so peculiar about what they allow on the internest. But, having had some experience with young Chinese students, there if there is a way, the Chinese young moderns will have figured it out. You might try just asking some of them if there is a way that they can "lift" an app from your phone to theirs.
Meanwhile, I will ask some Chinese students I know what they would do.
