At Joonghwa Jeon, the main hall (Jeongjeon) of Emperor Gojong's palace, stood a pair of Hwajun. The Hwajun were silk flower arrangements built around the symbolic flower of the Yi Dynasty, a five-petaled red or white plum blossom. The huge vases containing these flower arrangements were called Yongjun, named after the dragon that adorned them. The Yongjun dragon vase was large enough to hold one Seom, or a standard sack of rice (47.6 U.S. gallons) and stood about 9-Ja, 5-Chi tall (about 2.8 m).
