First of all: start with the basics, make up the basics first, and then focus on reading and composition. Basic, the key is to recite the text and dictate the words; Primary school composition reading is mostly narrative, so we should pay attention to cultivating them to grasp the key points and clues according to the transfer of time, place and orientation, and answer questions according to these clues, and the primary school reading answers can generally be found in the original text; Composition, in general, is to remember one thing and write about a person. The requirements are not too high. Just write fluently. It is important that you write more about hydrology and comment on their compositions.
Secondly, find more books related to Chinese in primary schools, such as The Complete Book of Chinese Knowledge-Jilin Publishing House.
Finally, you should find two more people with training experience to work with you. Proper management is also an indispensable factor!
Okay ... that's about it.
I hope it helps you-I wish you success!
