I remember it was at 3A35 (3rd floor) of New Xigong. It is genuine and has a Japanese version.
I saw more than 400 Japanese DVDs of the 2005 concert there last year. I watched it twice and left. I don't know if it's still there.
There is also a group of photos of their performance in Shanghai in 2002, which is not very expensive.
I still remember a T-shirt signed by them in the window. I don't know whether to sell it or not.
I didn't pay much attention to the rest. There should be many small perimeters.
It is suggested to send a Japanese version, which is more expensive, but more meaningful to wf.
Or you can go there and ask what's special.
You can try Friday afternoon or Saturday and Sunday. I hope you can meet some people in Ying Yuanhui. They may be better suited to give you advice. If it is an aunt, it may not be very proficient.
