Hello, Miss Yang Qing. Teacher Yang Qing's teaching methods give him enough space for independent thinking. For example, he said that Mr. Yong Yang would reserve 20 minutes for them to think before each lecture, and 20 minutes is the most basic thinking time for a competition question. Even if it took him 20 minutes, he couldn't come up with a solution completely. But in the explanation behind Mr. Yong Yang, he responded to his own solution ideas pertinently, and he could quickly absorb the teacher's knowledge points and understand the structure and ideas of the whole problem at once.
