It's certainly good for Zhengzhou Mei Niang to take me to the valley. Bigu, also known as Quegu, Qugu, Juegu, Juegu, Jiegu, Jiegu and Xiugu, originated from Fang Xian's family's practice of not eating whole grains, that is, instead of eating whole grains, they filled their stomachs with drugs, food and other things, or fasted for a certain period of time, which was a common way of keeping healthy in ancient times. Whether to choose the valley is a personal choice.
