It is impossible to challenge the first season. There are many challengers in ordinary posts, many of which can be seen in our daily life. Very grounded. Moreover, the host Sa Beining, the judges Emil Wakin Chau, Dong Qing and Li Changyu are all professional judges, and the variety effect is very good. They are generous and polite, and they are admirable people.

What impressed me the most this season was a policewoman, a community policeman from Jilin Public Security Bureau in Dong Yanzhen. Teacher Li Changyu is the idol of the challenger. She worships Mr. Li Changyu very much and wants her teacher's approval. This policewoman has great confidence in herself, and she has integrity belonging to the police. The challenge is to identify people by their footprints.

After several links, the challenger can accurately write down this person's gender, height, age, shoe type and even leg type, which is very powerful. Even in bad conditions, the challenger is calm and confident, and has a strong gas field.
