520 wu erling
The origins of 520 day started when the Chinese started using the term “520” online to abbreviate “I love you”, similar to how English speakers use “ILY” or “ILU”. Why? When spoken in Mandarin, the phrase “I love you” (我爱你 wǒ ài nǐ) sounds very similar to 520 (wǔ èr ling). Soon, the equivalent date of May 20 transformed into a celebration of love, focusing on gift giving. 520 day is also seen as a day to send gifts and messages to dear friends.
