Kuiba and the Twenty-four Solar Terms

How to interpret "it is difficult for friends to meet each other like the stars in the morning and evening"?

The blind spot of this sentence lies in "participation quotient". You can understand the meaning of "participation" and "quotient".

Shang refers to Shang Xing and Shang Xing, who are in the starry sky and will never meet each other. The meaning of opposition, distance, disharmony, inability or unwillingness to meet each other is extended.

Canon of "zhuan zhuan Zhao zhuan zhuan":

Gao Xin's family is Di Ku, the third of the "Three Emperors and Five Emperors" in China. Yan Huang, Yao Shun, was the ancestor of Shang and Zhou Dynasties. Di Ku has two sons. The eldest is called Quiber, and the youngest is called Stone God. When they lived together, they didn't like each other and thought about fighting every day.

Emperor Yao thought this was not feasible, so he moved Wei Xiao to Shangqiu and held regular celebrations with the big Mars (Antares, also known as "Chen Da" and "Long Xing"). Merchants inherited it, so Mars became a commercial star. The stone god moved to the summer and celebrated with the stars regularly. Later, he was succeeded by the Tang Dynasty to serve the Xia and Shang Dynasties.

In fact, from today's astronomy, it refers to Betelgeuse in the seven nights of Xiguan White Tiger, and Shang refers to Shinjuku in the seven nights of Dongguan Black Dragon, which is another name for Shinjuku. Betelgeuse is in the west and the heart is in the east. They all rise and fall in the starry sky and never appear at the same time.

This phenomenon is actually similar to the sun and the moon, but sometimes we can see "the sun and the moon are in the same sky" in the morning or at night, so it is more noble to use "participation in business".

"It's almost as difficult for friends to meet each other. As for the stars in the morning and evening," it means "life can't always be separated, just like the stars in the west and the stars in the east."

This idiom also comes from here. For thousands of years, there have been countless poems with the word "participation in business", and most of them are used together, because the word "participation in business" has solidified into a meaning that is difficult to meet, distant and discordant.

For example, Bai Juyi's "Five years with the same day and night, don't be a businessman."

Li Bai's "unintentional thing is still like this, and businessman Hu Nai is looking for heavenly soldiers."

Yuan Zhen "The shadows are the same at the beginning, and the business participants are divided." "Participants are in the sky, and Hu Heyue is on the ground."

Liu Zongyuan's Wind Platform Exposes Light, Ashes Discard Participants.

Du Fu still used his original intention here, expressing the feeling of not seeing friends for a long time, and there is absolutely no disharmony. Because this poem comes from his "Give Eight Guards to Chu Shi":

It's hard to meet a businessman if you haven't seen an old friend for years. When I was a teenager, but now these boys and girls are in a row. This feeling of mixed feelings in life can only be drunk.

The content of the poem is not complicated, so I won't explain it one by one.
