What is the Chinese number for I love you?

Why 520 Means "I Love You" in Chinese

Ever received a text with "520" and wondered what it meant? In China, this number isn’t just a random digit—it’s a sweet, modern way of saying I love you.

The phrase "520" is pronounced wǔ èr líng in Mandarin, which sounds remarkably close to wǒ ài nǐ—the Chinese words for “I love you.” It’s a classic example of how language evolves playfully, especially in the digital age. Just like “ILY” or “<3” in English texts, “520” has become a shorthand expression of affection, widely used in messages, social media, and even romantic gestures.

But the sweetness doesn’t stop at 520. You might also come across 5201314, an extended version that packs even more meaning. While 520 stands for “I love you,” the “1314” at the end—pronounced yī sān yī sì—echoes yī shēng yī shì, meaning “for a lifetime” or “forever.” So, 5201314 essentially translates to “I love you for a lifetime”—a powerful little code for lasting love.

These number combinations have become so popular that May 20th (5/20) is now celebrated as a sort of unofficial Valentine’s Day in China, with couples exchanging gifts, going on dates, and sharing digital tokens of affection.

So next time you see “520” pop up, don’t just read it as a number. It’s a quiet, clever whisper of love—spoken in digits. And sometimes, that’s more than enough.
