Milestone Notes

520 = "I love you" (a number homophone): This tradition comes from Chinese internet culture, where the digits "5-2-0" (wǔ-èr-líng) sound very close to "wǒ ài nǐ" (我愛你), meaning "I love you." As a result, May 20th (5/20) has become an unofficial "Internet Valentine's Day" across Chinese-speaking online communities.

1314 = "for a lifetime" (a number homophone): The digits "1-3-1-4" (yī-sān-yī-sì) sound similar to "yì shēng yí shì" (一生一世), meaning "one life, one lifetime" or "forever." It's a popular way to express an eternal commitment.

5201314 = "I love you for a lifetime": This combines both homophones — 520 ("I love you") and 1314 ("forever") — into one number that couples often use in gifts, red envelopes, and anniversary dates to mean "I will love you for my whole life."

100 days: A widely celebrated milestone in Asian dating culture, especially popular in South Korea, where couples mark their first 100 days together ("baek-il").

1,000 days: A milestone symbolizing a long and stable relationship.
