Can I drink tap water from Sa shop in Nha Trang, Vietnam?

You must have been misled by the tour guide. What they said is serious. How can I put it? You should also travel there with a group. If you are with a group, you will basically stay in a hotel with three stars or above, and the sanitary conditions are good. However, most people don't drink raw water directly except seawater. After tasting the water released from the hotel, it doesn't make much difference, but I still suggest taking Huoxiang Zhengqi Pill. After my analysis, the main reason for diarrhea may be that it is hot there. Go back to the hotel to drink tap water after going out. I was so hot and sweaty that drinking raw water directly would definitely cause diarrhea. After all, you can't drink raw water directly in China. Attached is a photo of the hotel location.
