"There is no end to the sun's arch, and the contribution will eventually go to the sea" means "perseverance, rewarding diligence by heaven", which encourages people to be diligent and enterprising.

There's no end to the sun's arch.

There's a famous saying: It's better not to be a general for ten years than not to arch for a day. As long as you work hard and persevere, you will make a little progress and progress like a pawn every day, and you will eventually achieve something.

Tang donated

Tang, which means in vain. Donate in Tang dynasty, which means wasting and abandoning.

Don't donate

In Buddhist, it means that the effort you put into something will not be wasted. All the merits and efforts in the world will not be paid in vain, but must be rewarded.

Gong Bu Tang donated it from Hokkekyo Guanyin Bodhisattva: "If all sentient beings worship Guanyin Bodhisattva respectfully, they will not donate it, so all sentient beings should receive the name Guanyin Bodhisattva." Later generations gradually wrote "Fu doesn't donate to the Tang Dynasty", and also expanded the "Fu" simply referred to in the scriptures into "Gong" that can refer to all efforts.
