What does the second and fifth eyes mean?

Two or five eyes: It is one of the vocabulary of Peking Opera. In Peking Opera, there are two-pan-three-eyes, two-pan-four-eyes, two-pan-six-eyes, but there are no two-pan five-eyes, so it is referred to as two-five eyes. Therefore, in Beijing dialect, "two plates and five eyes" (referred to as "erwuyan") means out of tune.

"Erwuyan" means "not so good", Shanghainese say "yeah eh". Among craftsmen, those who are clumsy are called Erwuyan. When I worked in a factory in the past, I would always hear people say which master was more skilled, but when I encountered a technical problem, I was stunned. Later, I returned to the team and interacted more with artists. I often heard calligraphers talking behind their backs about whose calligraphy, let alone mentioning it, would be worthless if they picked it up a few times.

Not knowing much about a thing, only knowing one thing but not knowing the other, being proficient in everything but sparse in everything, is just two or five eyes. When it comes to learning, Mr. Deng Youmei is an expert. If you ask him about old Tianjin Wei, there is nothing he can’t tell you. What happened in which year and month? Who is the mayor of Tianjin in which year and month? One word is accurate, knowledge! It’s impossible not to admire him.

Shanxi people talk about "two or five eyes", which means those drivers who don't pay attention to the five big and three thick ones, or those "road killers". (Example: The principal held a meeting to talk about student safety, "There are so many eyes on the road now. They all learn to drive for two or three days and start driving right away. Some of them haven't even taken the driver's license test. They dare to go on the road after getting a license. So. Students, when you cross the road, you must pay more attention to the situation on the side of the road. You would rather stop for three minutes than rush for a second.”)
