1. Shrimp can be used fresh or frozen, but it must be raw. When frying shrimp, cut the back of the shrimp and roll it into beautiful shrimp balls. Those who are too lazy to remove the shrimp line can pretend that it doesn't exist, so-called unclean, and they won't get sick after eating it. 2. Cucumber plays a decorative role here, and it can also bring fresh taste. If you are too lazy to slice, you can also skip the cucumber. 3. Dry-baked prawn sauce is salty, and no salt is needed. If there is no dried shrimp sauce, garlic and lobster sauce can be used instead, but the sauce should be put less, so that the dish will be light. 4. It is best to use fresh litchi. If you use fresh litchi, you can add a little sugar when thickening. If you use canned litchi in syrup, don't add extra sugar, otherwise it will be too sweet. Litchi should be put at the end, just stir-fry, shrimp is cooked quickly, so the cooking time of the whole dish is short and fast, in one go. In order to prevent confusion, please prepare all kinds of seasonings and thickening juice in advance.
