Lin Junting is not a liar. There are so many training courses (more than 20). This man not only has a good foundation, but also has many fantastic ideas. I especially admire his concentration and persistence. We young people should study hard with him. If it is a liar, will it last so long? Then the students who participated in the whole country complained ... and participated in many courses, and the results were very good. The technical concept is really good. No one is perfect.
