I want to write a calligraphy for the competition. What should I write?

If you underestimate it, you might as well write a sentence: "Calligraphy and calligraphy are close friends, and poetry and books are elegant and elegant." If you really want to write four words, you can also write them like this, for example: Qin Yunshu is born, realistic and innovative, free from vulgarity and erudition, sincere as a god, purple gas from the east, auspicious and virtuous, plain and pure, and heaven rewards hard work. But you should use traditional and other books. I hope I can help you.
