Hi Astrid :)

Maybe, you could take the part time job while you look for somewhere that will take you permanently.?

There are a lot of Philippines teachers in China, maybe you could try and get in contact with some of those. As they are non-native English teachers too.

I don't think a part time job will be able to offer you the security of a working visa and residence permit. You may have to put up with it for a short time til you find something more permanent?

Sorry I couldn't be more help. Good luck!
