negative example
The teacher on the other hand is an idiom, and the Pinyin is f à NMI à NJI à oyu á n, which comes from some historical experiences of our party.
allusion
Mao Zedong believed that 95% of the country was the people and 5% the enemy. In every movement, we should unite 95 percent and strike 5 percent. Instead of exterminating 5% of the enemy physically or separating them from the 95% of the people, we should let them stay among the masses, be supervised, work as coolies, and act as "teachers of the opposite". It's like killing a chicken in front of a monkey and hanging it around the monkey's neck forever. The intention is obvious.
source
Mao Zedong's "some historical experience of our party" said: "it is the face to face teacher of the people all over the world."
