According to folklore, Tongbai Mountain has a medicinal farmer called the platycodon, and goes out to collect medicine every day. One day, he just entered the mountain, and a fragrance came out. Looking at it, it is a wild daisy that grows on the cliff, and it dances in the wind. Suddenly, the wild daisy was stepped down by a wild deer. The kind of platycodon is very distressed. He climbed the vine with his hand and used his strength on the ankle cliff. He climbed up and lifted the wild daisy. Unexpectedly, at this time, one foot was emptied, and the platycodon fell from the cliff. In the coma, I was faintly heard that someone called the bellflower brother. He blinked and saw a woman with a flower like jade staying by his side.
