In Lu You's poem "Ode to the Plum Blossoms", the sentence that expresses that although he has suffered misfortune, he still remains "pure in nature and comes and goes in a pure state" is:

Bu Suanzi 1

Yong Mei

Song Dynasty - Lu You

Beside the Broken Bridge Outside the Post Office

Loneliness is endless Lord

It is already dusk and I am sad alone

More wind and rain

I have no intention of struggling for spring,

I will let everyone be jealous

Falled into mud and crushed into dust

Only the fragrance remains the same.

The high-spirited and upright sentence in the poem that maintains the principle of "coming and going clean again" is:

There is no intention of struggling for spring, and once everyone is jealous. It fell into mud and was crushed into dust, but only the fragrance remained the same.
