I tutored two international high school students in Shanghai in 2023, helping them improve in subjects such as English, mathematics, and geography. For 6 months, I helped them with their homework and bedtime preparations every weekday evening. My sister has two children (one is 7 years old and the other is 2 years old), and I really enjoyed playing with them and taking care of their lives. I realized that taking care of children requires great care and seriousness, and I gained a lot of happiness in the process of getting along with them.
