Which month does it start to get warmer?

Generally, it will be warm around March, but the temperature in the northern region will not start to pick up until at least around Tomb-Sweeping Day. As far as the radiation intensity of the sun to the earth is concerned, the winter solstice is the smallest and the summer solstice is the largest. Around March, coming to Chunwu means that spring has just arrived and the temperature has just warmed up. Don't take off your cotton-padded clothes too early.

In the eyes of northerners, southerners are sunny and warm in winter, so they can take a thick coat when they go out. In fact, the winter in the south is wet and cold, which belongs to the magic attack. Outdoor heating basically depends on shaking, and it depends entirely on its own cold resistance.
