"As the clothes get wider and wider, I will never regret it, and I will feel haggard because of the beauty." This is a kind of persistence in pursuing the truth unswervingly on the established path, and "no regrets" for it, And "gaunted" by it. There is not only physical suffering here, but also mental tempering. As Wang Guowei said, one can even "sacrifice the well-being of one's life" with "no regrets".
