Crazy English is a unique English learning method invented by Li Yang. He advocates crazy speaking and watching English. For example, he used to shout out 40 English sentences on his way to work. In addition, Crazy English has some seemingly strange methods, such as learning English with gestures. Generally speaking, Crazy English shows us a new way to learn English, which has been successful for many people. But in the later period, after the method became famous, there was no lack of speculation. I tried crazy English for a while before, and I felt the effect was not bad. It can stimulate people's interest in learning English. However, it is still necessary to analyze specific problems and try your own situation to see if it suits you. Don't blindly follow the trend.
