I was cruising the web looking at various sites when I found an interesting promotion video. It is a pretty informative video showing what a Mainland Chinese punter (in video they used a Japanese stand-in) would get if used he this new website,
www.fengyuelou-tokyo.com, that was created by a Japanese crew who studied in China. They said Japanese AV girls are available too.
The website is quite informative (is only in simplified Chinese, no English) but has currently suspended service because of COVID19. I guess when international traveling between China and Japan has returned to normal, this website will go back to work. By then I hope someone here would have given the service a try.
