Brother. Generally, grilled fish can sell for about 25 kilos. A fish of two Jin. It's about 50 when you serve. It's like this in my shop. For example, around 60%. Grass carp, sturgeon and crucian carp can be used. I have Wang Hua's grilled fish technology CD. I can send you a set if you want. I just learned Wang Hua's authentic grilled fish technique.
