How to stir-fry onions:

1. All ingredients (onions, bacon, light soy sauce, salt, seven-flavored Tang Xinzi).

2. Slice onions and cut bacon into strips.

3. Heat the oil and fry the bacon.

4. Add onions and stir-fry together.

5. Stir-fry until the onion aroma comes out, add salt and light soy sauce, stir-fry evenly, cover and simmer for half a minute. (Let the onions fully absorb the fresh flavor of the light soy sauce).

6. If you like spicy food, you can sprinkle in a little shichimi tangxinzi (a spice made from chili powder, sesame and other materials). Remove from pan and plate.
