Odd numbers feature heavily in Vietnamese life – they can be lucky or unlucky, depending on their context. Here’s a quick guide:
- When lighting incense, choose an odd number –either 1, 3 , 5 or 7 sticks. It’s unlucky to light an even number of incense sticks.
- Don’t repeat an unsuccessful attempt more than 3 times.
- Don’t leave on the 7th, 17th or 27th day of the lunar calendar and don’t return home from a trip on the 3rd, 13th or 23rd day of the lunar month. Breaking this rule could result in low sales if you own a shop, or an accident if you’re driving. (If you’re not superstitious, plane tickets are cheaper on these days!)
- It’s bad luck to have 3 people in a photo – opt for 2 or 4 for safety.
