A proverb that has been passed down for thousands of years: "In nineteen two-nine, do not take action; in ninety-nine, forty-nine, you walk on the ice; in ninety-nine, sixty-nine, you look at the willows across the river; in ninety-nine, eighty-nine, you wash your hands across the river; in ninety-nine, eighty-one , The old man is standing on the wall, not afraid of being cold, but afraid of being hungry. "

Jiujiu Song

From nineteen to twenty-nine, the fan never leaves his hand;

Two. Nine-one-eighth, take off your hat and put on your robe;

Three-nine-twenty-seven, sweat dripping from going out;

Four-nine-thirty-six, roll up the mat and sleep in the open air;

Five-nine forty-five, the hot autumn is like a tiger;

Six-nine fifty-four, it is not too late to enjoy the cool air;

Seven-nine sixty-three, touch the bedside sheets ;

Eight-nine-seventy-two, putting on a coat in the middle of the night;

Nine-nine-eighty-one, every family is laying coal foundation;

Nine-nine plus one-nine , has passed the Mid-Autumn Festival.
