If we don't start now to 16 the cultivation of non-intelligence factors, it will not only affect the development of the 17 of teenagers, but also affect the quality of a whole generation. Some experts have put forward 18 about how to cultivate students' non-intelligence factors. First, parents and teachers should 19 understand teenage psychology.
