"The road is long, but you can reach it if you work hard; no matter how big the task is, it will be achieved if you persevere" is a famous saying from the ancient Chinese writer Cao Cao. It is usually used to express encouragement and support for pursuing goals and achieving success. This sentence can be explained from the following aspects:

The road is far away, but you can reach it if you follow it diligently: "Tao" refers to the correct method, the right road or the right direction. "Guyuan" means that the right path is usually not a shortcut, but requires a long period of time and effort to achieve. "You can get there" means that as long as you persist in pursuing the right method, the ultimate goal can be achieved.

Although the task is huge, perseverance will lead to success: "Although the task is huge" means that the goal may be very large or arduous. "Persistence will lead to success" means that as long as we can persevere, remain unwavering, and overcome difficulties and challenges, we will be able to achieve our goals.

Taken together, this famous saying encourages people to stick to the right path and persevere unswervingly in the process of pursuing goals and achieving success. No matter whether the goal is difficult or not, as long as you work hard and persevere, you will eventually succeed. It emphasizes the importance of persistence, patience and confidence on the road to success, while reminding us that success does not happen overnight and requires persistent effort and pursuit.
