1 This number is betel nut. I know this may offend many people who like eat areca, but I really don't like it. I feel a smell in my mouth, which really lasts for a long time, and sometimes it's disgusting.
The second is Houttuynia cordata Thunb, which is rare in the north. Generally, southerners prefer it. I tasted it once on the trip, and the locals said it was delicious, but when I ate it, my mouth smelled of fish, and sometimes I felt a stinky smell. When I chewed it carefully, a faint nausea surged from the bottom up.
The third should be dark chocolate. Usually the chocolate we eat is processed with sugar or seasoning, which looks sweet and delicious, but dark chocolate is the real taste of chocolate. First of all, it is bitter, and it also has the taste of Chinese medicine. If you have drunk traditional Chinese medicine, you must know this feeling.
The fourth is snake grass water, which is famous for its unpalatable degree on the Internet. There is a story that snake grass and water are terrible everywhere. I may have tasted it myself out of curiosity, and I don't think I will drink a second sip in my life.
These are all things that I find difficult to swallow during my trip, so don't be too curious when traveling.
