How to draw Han Xiao's mind map

As early as the Eastern Zhou Dynasty, the Spring and Autumn Period and the Warring States Period, the working people of the Han nationality had the concept of "being far away from the north" and "being far away from the north". Subsequently, people divided the year into 24 equal parts according to the natural phenomena such as the beginning of the month, the running position in the middle of the month, the weather, the growth of animals and plants, and gave each equal part a proper term, that is, the 24 solar terms.

Han Xiao is the 23rd 24 solar terms, and there are many poems about Han Xiao. This is a very famous poem by Du Fu, "Han Xiao Zhou Zhong Zuo".

Rowing after the Cold Food Festival

Du fu in Tang dynasty

In the cold wind, there is hardly a bite of rice, sitting on the ground, sitting on the ground, the crow is old, sewed many times, and wears a brown hat on his head.

Spring water, rivers, so floating on the boat is like sitting in the clouds; My body is getting weaker and my eyesight is dim. Looking at the flowers on the shore is like a mist.

The listless curtains saw butterflies flying by; Seagulls skimmed over the rapids.

Standing in the direction of Tanzhou, looking north, looking straight at Chang 'an, the sky is like a white cloud, and there is a van parked there, suddenly worried.
