The small vendors at the entrance corner of the health market mainly sell sweet potato balls and sweet potato sticks. They sell them from afternoon to evening. Due to the limited amount of frying at one time, you often have to queue up, but you don’t have to wait for long. You can choose various flavors of sweet potato balls. Personally, I think the taste is more balanced when paired with plum flour, and the sweet potato balls themselves are chewy and the outer skin is crispy, making it a delicious snack.
