If you think that hotels in China put signs with Latin alphabets to let people who don’t know Chinese to understand the signs, many people will agree with you. But not this hotel. If you don’t know Chinese or pinyin, you are bound to fall in the bathroom because it say “be careful of slippery floor”!
50 cm away from the above sign is the one below. When I shower, I shower, and I do not pull the glass door, let alone lightly.
