Sorry !! I don't know how to type in Chinese. So, I reply you in English. Hopefully, you don't mind.
You're right. My husband & I go out for work daytime. So, my son is taken care by my Indonesia maid. Then, we will instruct him to do the homework first and check / make correction at night. During his childhood time in Kindergarten, we had bought a lot of exercises (extra) for him to do. Even though during past summer holidays, he also needed to do at least one exercise for English, Chinese, Maths & Social studies everydays.
