Legend of the Meridian Terrace
The First Emperor constructed the Cloud Bright Terrace, gathering rare woods from all directions and seeking skilled craftsmen from across the world. From the south, he obtained the Jade Trees of Yanqiu, the Burning Sands of Li River, the Vermilion Clay of Bendu, and the Plain Bamboo of Yungang; from the east, the Brocade Cypresses of Congluan, the Dragon Pines of Piaosui, the Star Zhe Trees of Han River, and the Catalpas of Wanyun; from the west, the Floating Gold of Louhai, the Feathered Jade of Langyuan, the Rosy Mulberries of Dizhang, and the Round Counters of Chentang; from the north, the Dry Lacquer of Mingfu, the Patterned Catalpa of Yinban, the Black Soul of Qianliu, and the Fragrant Jade of Anhai. Thus, rare and exotic treasures were collected together. Two men ascended into the void and climbed the trees, wielding axes in mid-air. Construction began at the Zi hour and was completed by the Wu hour. The people of Qin called it the "Meridian Terrace," also saying that a terrace was built at each of the Meridian locations (north and south); these two explanations are questionable.
Note: The First Emperor once gathered rare treasures from the world. From the south, he obtained the Jade Trees of Yanqiu, the Burning Sands of Li River, the Vermilion Clay of Bendu, and the Plain Bamboo of Yungang (four treasures); from the east, the Brocade Cypresses of Congluan, the Dragon Pines of Piaosui, the Star Zhe Trees of Han River, and the Catalpas of Wanyun (four treasures); from the west, the Floating Gold of Louhai, the Feathered Jade of Langyuan, the Rosy Mulberries of Dizhang, and the Round Counters of Chentang (four treasures); and from the north, the Dry Lacquer of Mingfu, the Patterned Catalpa of Yinban, the Black Soul of Qianliu, and the Fragrant Jade of Anhai (four treasures). It is said that at that time, two people wielded axes to build the terrace, starting at the Zi hour and finishing at the Wu hour, taking only six double-hours (12 hours), hence the name Meridian Terrace. Another theory states that it was built in the Meridian locations (north-south), with one terrace built in the south and one in the north, hence the name Meridian Terrace.
