Will Thai authorities approve further 30-day visa extensions for tourists due to COVID-19?

Hi everyone. I was wondering if anyone has any advice. My family and I are in Thailand as tourists. We have already done the 30 day extension and we got visa extension request letters from our embassies and will try to get another 30 days soon. Do you know if the authorities are likely to approve further 30 day extensions (assuming we get new letters). Long story short, we are residents in China (our whole lives are there - our apartment, all of our stuff, our kid's school...our cat!), but the Chinese authorities just temporarily banned foreigners (even legal residents such as us) from returning. I don't know how long this ban will be in place for. The problem is we literally have nowhere else to go. My wife and I are from different countries, so China is the only place we all have legal residence....and we're not allowed there!!! All other countries in the region (especially places we'd risk being stuck) seem to be closed. Jetting off further afield also makes no sense as China is so close and it might not be possible soon to travel back when the ban ends given the massive reduction of flights. Any advice would be much appreciated!
