"Even sesame seeds can be considered as oil", do you agree? If you agree, then you and Wang Xi (played by Feng Gong) are comrades, so you must also agree that "a team leader is also an official"!
Although in the eyes of many ordinary people, Brother Xi, this team leader, is just a minor role between soldiers and officers, Wang Xi, with his notable awareness, doesn't see it that way. He always holds himself to the standards of an official, and even more strictly. Wang Xi's famous saying is: If we don't regard ourselves as officials, then no one will regard us as officials!
