Every country has their own manners. And I'm going to talk about some Taiwanese table manners.
I believe that you've been to a wedding feast. You can see lots of table manners there. For example, don't put your chopsticks upright in your rice. Chinese people think it looks like incense stuck in the ash of a censer. This only happens when you're worshipping your ancestors. When you want to put down the chopsticks, you should put them flat on bowl or on the table.
To give another example, don't start eating as soon as the food gets on the table. It's very impolite to eat before the elders start eating. You should wait until the host tells you to start, and the elders have already tried it.
There are many kinds of snacks in Taiwan. They are all very special and representative. In my opinion, "stinky tofu" can best represent Taiwanese food. Because when we introduce it, most of the foreigners know it. They think it smells awful, but it tastes excellent with kimchi. In short, stinky tofu represent Taiwanese food the best.
