Is Anyone here from Hong Kong / Mainland China and Knows How to...

I have a very close person to me who has just lost someone very close to them. This person lives in Hong Kong and the person who passed away, lives in Shanghai.
Is anyone here from Hong Kong / Mainland China and knows how to get to Shanghai from Mainland China to attend the funeral service?
The travel restrictions are strict. If anyone knows, please let me know, ASAP.

Thanks

Shanghai is not very stricted, but you need some healthy code in mobile so that
you can go with the railway,etc.
