What about the fish in Dongting World?

In Malan Mountain, a fish restaurant, Dongting is delicious all over the world. Fresh live fish is really delicious, and the food is delicious. There are always many people in the evening, the box is often full, the service attitude is acceptable, and the serving speed is slightly slow. I wonder where these so-called Qiandao Lake organic fish came from? Because when we went to Qiandao Lake, the locals told us that the so-called Qiandao Lake live fish in other places were not true. . .
