A：Why don't we Chinese have our own Valentine's Day?我们中国为什么没有自己的情人节呢?
B：Of course we have. It's on the seventh day of the seventh lunar month.我们当然有，是在农历七月初七。
A：Oh? Why is that day?哦?为什么是那天?
B：It is said that the Cowherd and the Spinster, the lover stars in heaven, can only meet on the seventh Eve, so this day has become the Lover's Day.据说牛郎星、织女星只能在七夕相会，所以这天就成了情人节
