The emperor took huge efforts to search for art masters. He established the "Hanlin Huayuan" (翰林畫院; "Hanlin imperial painting house") where top painters around China shared their best works. The primary subjects of his paintings are birds and flowers. Among his works is "Five-Colored Parakeet on Blossoming Apricot Tree". He also recopied Zhang Xuan's painting "Court Ladies Preparing Newly Woven Silk", and Emperor Huizong's reproduction is the only copy of that painting that survives today. Emperor Huizong invented the "Slender Gold" () style of calligraphy. The name "Slender Gold" came from the fact that the emperor's writing resembled gold filament, twisted and turned. One of the emperor's era names, Xuanhe, is also used to describe a style of mounting paintings in scroll format. In this style, black borders are added between some of the silk planes. In 1114, following a request from the Goryeo ruler Yejong, Emperor Huizong sent to the palace in the Goryeo capital at Gaeseong a set of musical instruments to be used for royal banquet music. Two years later, in 1116, he sent another, even larger gift of musical instruments (numbering 428 in total) to the Goryeo court, this time "yayue" instruments, beginning that nation's tradition of "aak". Emperor Huizong was also a great tea enthusiast. He wrote the "Treatise on Tea", the most detailed and masterful description of the Song sophisticated style of tea ceremony. Emperor Huizong's famous descendant was Zhao Mengfu through his daughter Zhao Jinluo.
