My child has been taking math classes with Euler's math teacher Liu Heng for three years in junior high school, and got 1 17 in the senior high school entrance examination, which has always been the first and second in the class. Mr Liu Heng graduated from Tsinghua University. He is very handsome. He teaches mathematics thinking very well. He is in the Euler Math Tutoring School in Jinbi Road, so you can learn about it. There is a special senior high school entrance examination class in grade three.
