Walking on the ice in March, 949: March, 949 is the coldest season of the year, and the river is covered with thick solid ice, so pedestrians can walk on the river safely.

Watching willows along the river in May, 1969: The coldest time passed. When the weather began to get warmer in May, 1969, the willow branches planted by the river began to sprout, and everything gradually recovered to remove the winter depression. People could not help but watch willows.

The river opens in July and September, and swallows come in August and September: in July and September, the ice and snow begin to melt, and the frozen river surface will slowly thaw, and you will hear the gurgling sound. When the weather gets warmer in August and September, swallows will fly back from the south to nest and start a new round of busy and endless cycle.

Draw a circle on a square every day, there are cloudy days and sunny days. When the square is full, the cold disappears, which is called "99-99 table for eliminating cold".

There are also descriptions of nine hollow shadow characters, each of which has nine strokes. For example, "Liu Zhenbao in front of the pavilion" began to fill in the first stroke of the first word nine days ago, and every time he wrote a stroke later, a word became a "nine" after nine days, and nine words were used up after 81 days, which was called "Jiujiu Jiehan Sentence";

Others create nine-body couplets, each with nine words and nine strokes, such as "the autumn screen bar trees in the old city are withered and glorious, and the courtyard is quiet in spring." Put these calligraphy and paintings into spaces, and fill in one couplet and one couplet every day. When the whole couplet was completed, it was warm in spring in bloom, which was called "1999 Spring Festival couplets".
