Preparation:

1. Soak the rice noodles in warm water until tender. Boil for 3-5 minutes. Then, remove. Put vegetable oil over the noodles, and quickly stir so that the noodles will not stick together.
2. In a pot, boil the fish balls, jelly fish, morning glory, and tofu with the chicken stock. Then season with salted soybean paste and sugar.
3. When serving, place the noodles in a serving dish and pour the soup over it. Season with fish sauce, sugar, chilli powder, and vinegar as desired.

Note : If you prefer dried "Yen Ta Fo", just exclude the chicken stock from the dish.
