• 

  Avoid black and white at celebrations because they are associated with mourning and funerals

• 

  Wear and use red for luck, celebrations, weddings, and Lunar New Year

• 

  Avoid giving gifts in sets of four, and prefer auspicious numbers such as 2, 6, 8, or 9

• 

  Seek the number 8 because it sounds like prosperity or wealth; 9 is also favoured for “lasting/everlasting” connotations

• 

  Avoid the number 4 because it sounds like “death” in Cantonese, so many buildings skip 4th, 14th, 24th, and similar floors

• 

  Apologise before urinating in the wild so you do not offend spirits living there

• 

  In the forest, offer salt or pepper to unseen spirits without looking up if you want good luck or windfall

• 

  Put chilli and onion under a tree to “ask” the rain to stop for outdoor events

• 

  After attending a funeral, people should not go straight home and should wash or sprinkle water to avoid bringing spirits back

• 

  Pregnant women should avoid funerals to protect the unborn child from negative energy or spirits
