Zu Feng is introverted and doesn't talk much. On weekdays, I like to practice calligraphy, seal cutting, copy classics, go to see operas and read books. He has always liked to write letters, and he wrote home letters to his parents every week during his college years to report his safety. The letter written by Zufeng to his wife with a brush is small in font and beautiful as classical poetry. Zufeng is naturally interested in inkstone and stone because he loves writing and seal cutting.
