Hylocereus undatus, a symbol of Huangpu's Shenjing village, has been planted in the area for more than 100 years.
Locals in the village prefer to use the sun-dried hylocereus undatus to make soup, which is of higher quality than the heat-dried one.
The soup made with hylocereus undatus is renowned as a cooling soup that is known for strengthening lungs, relieving coughs, and clearing phlegm.
