Taiwanese Food and Table Manners

Recently, I learn many things from the food project. My teammates and I made the steamed burgers which we think could represent Taiwanese culture. Although it's famous and delicious, I don't like it with pickled cabbage. In fact, I think pickled cabbage has a strange smell.
In addition, I interviewed my family about what food could best represent Taiwanese culture. I found that people at different ages have different thoughts. Most of the elders think it's "rice porridge" or "sweet potato", but the middle-aged persons think "stinky tofu" or "rice with stewed pork" is the most popular. To tell the truth, I like the "pearl milk tea" myself, because when we introduce it to the foreigners, many of them know it's Taiwanese food. In short, there's lots of traditional and special food in Taiwan.
I also learn about table manners. When we eat in Taiwan, there are many table manners we should obey. For example, we should let elders sit down first, don't start eating as soon as the food gets on the table and try everything that is offered to us. Besides, we don't put our chopsticks upright in our rice, this is what the elders care most. But if we don't want to use the chopsticks, what should we do? Don't be nervous. When we aren't using chopsticks, or have to drink, or talk, we can leave them flat on the table. Although there are many table manners, it's our precious culture.
