Yes. We can. But like I said, we have no home in either country. We'd soon run of money (getting there, the insane cost of living there). And, as I said, we'd probably not be able to get back to our actual home when it reopens (not sure when, but it might only be a month or two...of course it could be longer, but nobody knows).
US/UK. However, going back to either would be a really bad idea. Other than the fact that both countries are imploding, we don't live there and have nowhere to stay. Plus, as I said, we'd likely find getting back to China almost impossible soon.
Sure. For a limited time. Just like here. Except we'd then be half a world away from China (where we need to get back to). I know Thailand is not responsible for us. However, our respective embassies can only give advice for us, not as a family as a whole. Their advice is to return home. However, China is our home.
