Quite a few. You want to find a good credit, go to Haopu for training and find Mr. Huang. It's really good. I feel that they are doing it with their hearts. I signed up for level 3 at his place, but the other two are said to be not so good, unlike Hope! Seeing is believing, the training fee is about 3000 yuan, which is very expensive 100 yuan. Learning dietitian can make the same person live ten years longer. I think 300 thousand is worth it, hehe.
