Which traditional festival is closer to the best time to watch the tide in Qiantang River?

The spring tide in Qiantang River is the largest on August 18 of the lunar calendar, and it can be seen from the first day to the fifth day of the lunar month, and from 15 to 20 of the lunar month, so you can watch the tide on 120 days a year.

Every year on the 15th day of the eighth lunar month, the tidal bore in Qianjiang River is the largest, and the tidal head can reach several meters. When the tide came, the sound was like thunder, and the avalanche was spectacular. Especially around the Mid-Autumn Festival, guests from all directions flocked to watch the wonders of Qian Jiangchao, which was unprecedented.

Historical origin

Watching autumn tide in Qiantang has become a custom as early as the Han, Wei and Six Dynasties, especially in the Tang and Song Dynasties. According to legend, August 18 of the lunar calendar is the birthday of the tide god, so the tide peak is the highest. In the Southern Song Dynasty, the imperial court stipulated that the navy division should be inspected on the Qiantang River on this day. Later, they became accustomed to each other, and August 18 gradually became a tide-watching festival. Pan Lang, a poet in the Northern Song Dynasty, wrote in Jiuquanzi:

Long memories of watching the tide, full of people vying to see the river. I suspect that the sea is empty and drums are beating all around. Xiang Tao, the frolic in the frolic, stands upright and keeps the red flag wet. I don't see the dream a few times, but I am still chilling.

This poem is a true portrayal of the activities of "making waves" and "watching the tide" in those years.
