What day is November 11th of the lunar calendar?

The first day of October refers to the lunar calendar, that is, the Cold Clothes Festival. Literally, if the first day of 10 is cloudy (or rainy), then the sun behind it is more precious than gold. "The sun" refers to a sunny day with the sun, and "more expensive than gold" is a metaphor.

The implication of this proverb is that if the first day of October is cloudy, there will be few sunny days in that winter, mainly rain and snow. In other words, less sunny days mean warmer weather, less rain and snow, and the temperature will not be very high, and it will be colder that winter. Therefore, just from this proverb, the first day of October is cloudy, indicating that it was cold that winter.

"When the Chinese New Year comes, the sun smiles, there is no snow in winter, and it is as warm as spring";

In this proverb, "the sun smiled" refers to sunny weather, and "warm as spring" refers to a relatively high temperature, similar to spring. Therefore, this proverb means that the sunny weather on the day of the Cold Clothes Festival indicates that there is less snowfall in winter, the temperature is relatively high, and people's senses will be warmer. Therefore, only from this proverb, it is clear on the first day of October, which indicates that the winter is relatively warm that year.
