"If love lasts for a long time, you can't seize the day" comes from the seventh and eighth sentences of the ancient poem Que Qiao Xian written by the Tang Dynasty poet Qin Guan. The full text is as follows:

Thin clouds are clever, flying stars spread grievances, and yinhan sneaked into Chen Cang.

On the seventh day of autumn dew and autumn, it is time to meet, mostly those who are together in the world, but the appearance of husband and wife.

Common complaint against acacia, tender feelings like water, meet each other as if it were a dream, when it is hard to see the bridge.

As long as two people love us to the end, why covet my Heron?

Translation:

Thin clouds are changing in the sky, meteors are conveying the sadness of acacia in the sky, and I quietly crossed the distant and boundless galaxy tonight. Tanabata meeting in the autumn wind and white dew is better than those couples who are together in the world.

* * * v. Acacia, tender as water, short will be like a dream, can't bear to see the magpie bridge road when leaving. As long as two people love each other till death do us part, why do you want to be very much in love?

Precautions:

Thin cloud: light cloud. Trick: refers to clouds turning into various clever tricks in the air.

Flying star: a meteor. One refers to the morning glory and the weaver girl.

Han Yin: The Milky Way. Jumping: It's a long way. Darkness: Sneak past.

Golden wind and jade dew: autumn wind and white dew. Li Shangyin's Seven Nights in Wesin: "It comes from the blue and silver river, but it has golden wind and jade dew."

Forbearance: How to forbear and never look back.

Morning and evening: refers to getting together in the morning and evening. Song Yu's Gao Tang Mi came out.
