According to that dish, the head on the left side should be cooked (salted shrimp head, delicious shrimp head, shrimp head in tea king's bureau, dried shrimp head,,,,), and you can eat it directly without bringing any ingredients.
The one on the right is not the same, and the difference is very big. It is called (boiled prawn or picked prawn) and is eaten with boiling water.
It's not difficult to dip the ingredients: first, (seafood soy sauce10g, light soy sauce10g, water10g, ginger 5g) can be pulled by boiling, and if the salt is not salty enough, add (salt, monosodium glutamate and chicken essence) according to personal taste.
Remember: people who eat seafood and the like (sticky materials are best cooked and eaten).
