The name TWSBI is derived from the reversed initials of “San Wen Tong,” meaning “Hall of the Three Cultures” in Chinese. The Qianlong Emperor created a monument to house the three great masterpieces of Chinese calligraphy. The word “Bi” signifies the magic of writing instruments. Thus, the brand name was born — a tribute to the art of writing itself. Pronounced: Twiz-bee!
