What is Yu Shinan's "Five Musts"?

Yu Shinan's Five Essentials (Morality, Loyalty, Bo, Ci and Wen)

Emperor Taizong often said that Yu Shinan has "five unique skills", namely, morality, loyalty, erudition, literature and prose. "One thing here is enough to be a famous minister", "Southerners are born with talent and have five unique skills". Speak highly of him.

Yu Shinan (558-638), a native of Yuyao, Zhejiang Province, was one of the four great calligraphers in the early Tang Dynasty. Learn calligraphy with the wise and brave monk since childhood. The so-called "victory over mountains and rivers" means that he is convinced of Wang's brushwork. It was valued by Emperor Taizong and Li Shimin. Since the Tang Dynasty, emperors have imitated Wang Xizhi's calligraphy style. Emperor Taizong once asked Wang Xizhi's calligraphy with gold and silk, and the world competed for ancient books with the intention of offering them. Yu's calligraphy inherits more than creates, and Yu Shinan is knowledgeable, honest and sincere, and is deeply favored. Emperor Taizong vowed to learn from Wang Xizhi and Yu Shinan, which shows his great influence. Later generations have different opinions on "Yu Ti". His pen is round and square, soft on the outside and rigid on the inside, with little carving and anger, and his cursive script is almost a direct biography of Tang Wang's cursive script.
