What are the two words behind the spring rain, spring rain, clear valley, summer and heat?

2. Twenty-four solar term song full version should be: Spring rains startle spring and clear valleys, and summer is full and summer is full. Autumn dew, autumn frost, little snow in winter and cold in winter. The first half of the year is June 2 1 day, and the second half is August 23. The dates of the two festivals each month are fixed, with a maximum difference of one or two days.

3. There is another version of "Twenty-four solar term song": plum blossoms in beginning of spring are particularly bright, and apricot blossoms are particularly fresh; Lulin thunder, butterfly dance between flowers at the vernal equinox. When the kite is broken in Qingming Festival, there are tender teas in Grain Rain, mulberries like cherries in long summer, and silkworms in Xiaoman to cultivate fields. Before the awn seeds are raised into the palace, the rice flowers are like white training on the summer solstice; Summer breeze urges early-maturing beans, and Chi Pan enjoys red lotus in hot summer. Beginning of autumn knows how to make people fall asleep, and sunflowers smile in summer. The white dew returns to the geese, and the autumn equinox smells like osmanthus. Cold dew vegetable seedlings are green, and the first frost reed flowers are floating all over the sky; Beginning of winter reported good news, reported three rewards, and light snow and goose feathers flew in pieces. The snow is very cold, the plum blossoms are crazy in the wind, and the winter solstice is full of snow. Little cold wanderers are homesick, and they celebrate reunion at the end of the cold year.
