You can't get into the water during the Millennium solar term.

Yes, after the Millennium solar term, the temperature will gradually drop, especially at night, and the weather will become cooler. At this time, people are not advised to swim or bathe easily, especially in the northern region. Although the river may still be warm at noon, the water at the bottom of the river has become very cold. At this time, swimming in the water is easy to catch a cold or cause calf spasm, thus increasing the risk of drowning.

Therefore, after the Millennium solar term, in order to be healthy, try to avoid water activities. If you have to do water sports, you should make full preparations, including wearing appropriate clothes, bringing necessary medicines and equipment to ensure your own safety and health.
