How can a colleague make a humorous comment when he posts on WeChat about the antigen?

Antigen test can be hilariously posted on WeChat Moments like this: Report, we are all team leaders here.

In some containment areas, everyone needs to take an antigen test every day and do it before a nucleic acid test. Once a day is not enough, but twice in the morning and evening. During the nasal swab test, if there is a bar, it means it is negative, so the most popular saying is formed: report, we are all team leaders here and have a bar. The team leader’s line is related to the antigen test and the Young Pioneers’ line. The metaphor is vivid and impressive.
