Plain and comfortable is a person who works at sunrise and rests at sunset, and life is plain and unremarkable. Don't say it's really comfortable, and there is no noise in the city. I feel that life is particularly comfortable. I felt that I had a fight with the life of a wild crane in the clouds, but I didn't listen to what was going on outside the window. I feel like I'm just reading a sage book and doing whatever I want.
What is a breakthrough? The tight encirclement refers to the layers of encirclement. Breakthrough is breaking. In this expression, a breakthrough is to concentrate on attacking or counterattacking a point and opening a gap. Breaking through the tight encirclement means concentrating troops on attacking or counterattacking at one point, that is, opening layers of encirclement. For example, this battle is very fierce. Surrounded by the enemy several times, we finally broke through the encirclement and achieved safe transfer.
