A lot of exposure to English speech signals
This method says a lot of input "listening". We didn't have the conditions before, but now there are more and more audio-visual materials in the original English, and many children have grown up under the influence of the original cartoons.
Real and effective language interaction
This method is very difficult, because many parents receive exam-oriented English education. Not many people live in a real English environment for a long time. The words commonly used by native English speakers are different from those in our work.
