Calligraphy about school motto

"Self-improvement, morality and morality" comes from the hexagram in Zhouyi: "A gentleman is self-improvement; The terrain is Kun, and the gentleman carries things with morality. " Sports in the sky are only strong and healthy, accordingly, a gentleman should work resolutely and hard; The potential of the earth is thick and slippery, and the gentleman is tolerant. That is, life should be as tall as the sky, resolute and self-reliant, as thick, broad and virtuous as the earth. At present, Tsinghua University's school motto is "strive for self-improvement, be virtuous and carry things". In fact, "self-improvement and respect for morality" means that people should follow the example of heaven and earth and make continuous efforts in learning and doing business. It doesn't matter if you write two words separately. After all, they are two idioms. Let's open it separately. The office is "constantly striving for self-improvement" and the office is "generous and virtuous". For reference only.
