下一个一生一世是520下一个我爱你是1314
[xià yī gè yī shēng yī shì shì 520 xià yī gè wŏ ài nĭ shì 1314]
Here '520' stands for 'I love you' as its pronunciation resembles the phrase in Chinese. Likewise, '1314' represents 'forever'. The name means 'The next forever together is 520, the next 'I love you' is 1314', which implies the eagerness for eternal love with future dates to look forward to.
