How did mango come from?

Ear seed is one of the 24 solar terms, which originated very early. In the Spring and Autumn Period, the vernal equinox, autumnal equinox, summer solstice and winter solstice were first established, and then they were continuously improved. By the Qin and Han dynasties, the names of the 24 solar terms, such as ear species, had been established. Gao Wei introduced that in the taichu calendar Law of Han Dynasty, 24 solar terms were officially listed in the calendar. Generally, awn seeds are sown around June 6 every year when the sun reaches the meridian of 75 degrees. The ancient book "Waiting for the Seventy-second Month" once recorded: "The May Festival means that there are awns and crops in the valley."

Chen Sanmo, a scholar in the Qing Dynasty, also explained: "Mang is the last straw; Planting, crops also; It is said that the valley with awns can be planted at this time, so it is called awn seed, which is also the solar term in May! " That is to say, awn is the needle at the top of grass, indicating planting and sowing; The awn seed is a grain with awns, and it can be sown at this time. Rice cultivation is generally in the southern region where paddy fields are dominant. The northern region is dryland agriculture, and wheat is the main food crop. For the northern region, "awn seed" is the season when wheat matures, so the meaning of "awn seed" is also interpreted as "the wheat with awn is about to be harvested, and the rice with awn can be planted". Wheat harvest increased, including rice sowing in the south and wheat harvest in the north.
