Bulang astronomical calendar

After years of practice in production struggle, the ancestors of Bulang people accumulated a lot of knowledge about astronomy, calendar and weather changes, and summed up the original method of distinguishing orientation, season and climate.

The Bulang people have their own names for the sun, the moon and the stars. They know the orientation according to the ups and downs of the sun, the moon and the stars and the back of the tree. Usually at night, you can tell the direction and time by the position of the Big Dipper. You can tell the direction by the direction of sunlight during the day. On cloudy days, you can tell the direction by the growth of plants. For example, the smooth side of bark under direct sunlight is the east, the trunk behind sunlight is light green, and the side with some fresh moss is the west. More interestingly, the Bulang people still retain some primitive methods to distinguish between seasons and climate change. For example, an agricultural proverb says, "It rains when the moon holds an umbrella, and it dries when the sun holds an umbrella"; "Long sunny munches, rainy days come, long rainy munches, and the sky clears up"; Frogs cackle in the river, it's going to rain; "Flying ants fly to the sky, it will rain heavily" and so on. There is a bird in the mountains, and its name is Yue in Brownlee. It lives in seclusion in the forest on rainy days. If you see the bird jumping out of the forest on a cloudy day, it indicates that it will clear up.
