Wang Xiaolan, a social worker, said it well. According to the information found in the online examination in China, social worker Wang Xiaolan speaks well for the following reasons.

1, the teaching level is very high, which enables students to effectively understand the social work theory they have learned, while Liu Xiaochen is relatively young and lacks some social work experience, so he can't better convey his knowledge to students.

2. Paying attention to the communication between students, often stimulating students' thinking, and cultivating students' analytical and independent thinking abilities, Liu Xiaochen still relies on book education, and does not combine his lectures with practice.
