What is Yin Si?

Yin Si is a dialect. It means the weather is cold and cloudy, which is often used in spring and autumn. For example, when I first arrived in early spring, it rained a lot in March and the weather changed. It should be said that it is cold and rainy today. Dialect will say it's cloudy today, put on your down jacket!

In the early autumn, the autumn wind will blow and you will tremble when you go out. Oh, it's cloudy and cold today!
