Qu Yuan's famous sentence is as follows:

1. It's a long road, but it's Xiu Yuan, so I will go up and down for it.

This is a famous saying of Qu Yuan in Li Sao. It means "the road ahead is long, and it takes a long way to practice. I will keep trying to explore."

This sentence expresses a key philosophical concept, that is, actively face difficulties and challenges, be fearless of hardships, keep exploring and advancing, and never give up. It also tells us that it is not easy to achieve real success, and we must make painstaking efforts and unremitting pursuit.

2. I take a long breath to hide my tears, mourning the hardships of the people.

This sentence comes from Qu Yuan's Lisao, which describes Qu Yuan's deep reflection on the people's suffering and plight after suffering from wars, natural disasters and man-made disasters.

The whole sentence shows Qu Yuan's concern for the fate of the country and his anxiety about social reality, feels the hardships and pains of people's livelihood, and expresses the author's determination to do his best for the people.

3. Take a long sword and carry a Qin bow, leaving your head away from your heart and not punishing you.

This sentence comes from Qu Yuan's Nine Songs of National Mourning. During the Warring States period, the bow of Qin was the most powerful, and this poem refers to the strongest bow of Qin. "Punishment" means fear, fear. The whole sentence means: wearing a long sword and holding a strong bow, you are not afraid to go to the battlefield even if you are beheaded.

This sentence is a sacrifice song written by Qu Yuan for the soldiers who died in other countries, praising the fearless spirit of the soldiers who died for their country, and it is filled with heroic chivalry between the lines.

4. The water in the surging waves is clear, which can support my tassels, while the water in the surging waves is turbid, which can support my feet.

This sentence comes from Qu Yuan's The Fisherman's Songs of Chu. It means: when the water in Canglang River is clear, we can use it to clean our hats. When the water in Canglang River becomes turbid, we can only use it to wash our feet.

Qu Yuan compared the clearness and darkness of the world with "clear water" and "turbid water", and pointed out that people should be flexible and changeable, which is a more vivid statement of the philosophy of living with the same light and dust.
