Wash the onion, pumpkin, frozen corn, frozen green peas, cabbage, shrimp, and cucumber. Slice the onion, dice the pumpkin, shred the cabbage, and dice the cucumber for later use.

Melt the butter in a pot and sauté the onion until fragrant. Add the pumpkin, corn, green peas, shrimp, cabbage, and cucumber, and sauté until the vegetables are slightly soft. Add a pinch of salt, then pour in half of the water and bring to a boil.

Once boiling, add the chicken broth cube, hot and sour soup cube, and the remaining water. Bring to a boil again, taste, and add more salt if needed before serving.
