I posted just to ask about the visa rule.

@Chris ********************

These days China has a general attitude of not letting people out as much as possible, and policies could get even tighter any time, once I am in China, it probably won't be that easy to get out, that's why I am looking for a solution that would provide something before going there.

I don't have to be 100% sure about succeeding at a possibility before looking into its potential impact on other options in the future.

I assume you have a good reason to tell me "your question doesn't make much sense", which is probably to be helpful and suggest me to find a better way. While I appreciate your help, I'd also like to say my question does make sense, I asked it for a good reason-my intention of getting a long-term visa is to be able to return to Thailand from visiting my parents in China which could take a few months, at the moment due to covid China is not letting people leave the country for touristic purpose so you have to be working, studying etc. It might be more efficient to apply ED visa from China from the day I will actually be back in Thailand, but getting it in advance provides some form of certainty before getting into the land I might not easily come back out of.
