Looking at the 679 River along the river in May 1969, what weather is getting more and more?

As far as most parts of China are concerned, the weather was not the coldest when the 29th passed, but "1929, I can't reach it." At the end of April 9, it was almost the "Great Cold" solar term, so we said "March 9, freezing cats and dogs".

After May 9, the earth gradually rejuvenated and the weather gradually warmed from cold, so "May 969, look at the willows by the river; 7989, walking alone. " By 1999, it was already a "shock pad" solar term, so "the thunder of 1999 made a lasting noise."

The Origin of Jiujiu Songs

According to legend, as early as the Spring and Autumn Period and the Warring States Period BC, Jiujiu songs have been widely used by people. In many works at that time, there were records about Jiujiu songs. The original 99 songs started from "99.8 1" to "22.24", with 36 sentences.

Because it started with "998 1", it was named 99 Song. Ninety-nine songs further evolved into the multiplication formula we use today, and 45 sentences became "small ninety-nine".
