It's ok to buy jade with high cost performance in Ruili, but it's hard to say in tourist attractions and other places.

Judging from your description, it shouldn't be a problem whether it is true or not. The product quality should be ok, a little old. I wonder what the Taoist priest looks like. If there are pictures uploaded, I can take a look at them for you.

Or upload my photos directly from Baidu Hi.

I hope it helps you. Good luck!
