There’s a place around where I live in Banqiao that does it all. Straight razor shaving, mustache curling, decent men’s haircuts, you name it. Very reasonable pricing. No English though. I always feel like the people asking these questions never bother to walk around their neighborhood, quite a few people even asked about music shops, which are very easy to find … I’ve seen at least a half dozen barber shops in nearly every town I’ve gone into.
Edit, I should’ve mentioned that I don’t speak any Chinese. When body language doesn’t work I’ll use Google translate. Most business owners I’ve come into contact with care more about making money than small talk.
