A poem describe that dawn will always come, and that misery will alway pass.

a stone is a tool to sharpen its edge, and it turns dullness into profit.

fame and fortune tend to be poor and neutral, and disasters often arise from cleverness. The heavy snow presses the pine, and the pine is straight and upright. You should know that the pine is noble and clean until the snow melts. Although it's hard work, it's hard to blow out the crazy sand before you get to gold. The sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold. Jade grinds into many tools, and when the sword is pulled and buried, it will depend on heaven. Whether a husband is expensive or not, success or failure is not enough. It's a long way to go in Xiu Yuan, and I'll go up and down. Those who set great ambitions in ancient times are not only talented, but also determined to persevere.
