This kind of fish therapy hall is very distinctive, but I don't know if it is really good for your health. I feel that people may try something new and won't go for a long time, so it is difficult to be a stable source of tourists. Although business needs to be distinctive, it also needs demand. Speaking of which, it reminds me of drawing on the wall with special tools. People who don't have any painting skills can paint beautifully, as if it were called Tianyi Background. I think the paintings on the wall will catch on.
