1. An empty stomach is the most important thing, and you can only eat happily when you are ready.

2. Drink less water, preferably not. If you want to drink, you have to eat until the end. Try not to drink drinks, especially carbonated drinks, which will cause flatulence. Drink coffee if you want. It is said that coffee can help digestion.

Don't be distracted when grabbing food, and don't say hello to everyone you know. You know, maybe after a second, the food you want will be gone. You have to wait, and maybe you will never eat it again.

4. Eat less fat and greasy food, especially pork belly. Of course, there is nothing to say if you like it very much. Mainly because greasy is easy to get full.

5. Be familiar with the terrain. Remember where you like to eat, take the food and go straight to your goal without looking around.
