I've been living in Vietnam for almost a year, and there is a crazy amount of superstitions here. Some of them are eastern Asian, and some were proudly invented here.

- Number 4 is an unlucky number. 6 and 8 are lucky numbers. In fact, most wifi passwords here are 66668888 or 88888888.

- Don't stick the chopsticks in rice in the middle.

- Don't flip the fish as it mimics the fisherman's boat flipping.

- Burn a ton of stuff to help the diseased at Tet holiday.

- Don't boil the same water more than once.
