Mathematics is the language of the universe, and through it, we can unlock the secrets of existence.
数学是宇宙的语言，通过它，我们可以解开存在的秘密。
Don‘t bother fighting the old； just build the new.
Quality is remembered long after the price is forgotten.
——在上海中国国民党本部会议演说，1920年11月4日
Art is humanity's last line of defense.
