Antique/Vintage Chinese Wedding Basket - White w/ Jade tassel

Description

Antique/Vintage Chinese Wedding Basket - White w/ Jade tassel.
I know very little about this; my mom treasured it.  She had over 40 years.
It needs a cleaning. I have no idea the correct way to do that; I'll Leave to you.
The cover does not seat fully around; I believe it could be fully seated; but I fear damage if I try.
Paint is chipping; in decent shape for age. Please see all pics for true condition.  Any questions, please ask.
I ship to the continental US only.
