In "Living in the Mountain and Thinking of Shandong Brothers", the poet's homesickness in a foreign land naturally exists on weekdays, but sometimes it is not necessarily revealed.

The origin of the name "Chongyang" was named after "Yang is nine" in the ancient book I Ching. In the Book of Changes, "six" is defined as yin number, "nine" is defined as yang number, and "extreme number" means that the height of the sky is "nine times".
On the ninth day of September, the sun and every month meet on the ninth day, which means "the weight of 29", so it is called "double ninth". At the same time, the two yang numbers are combined, so it is called "double ninth". In the Ming Dynasty, Zhang Dai wrote "Night Flight" and said: "Nine is the yang number, and its day coincides with the month, so it is called" Chongyang ".
"Nine" is the Lao Yang, which is the anode number. The two anode numbers are combined, 1999 is unified, one yuan starts, and Vientiane is updated. Therefore, the ancients thought that Chongyang was an auspicious day to celebrate.
