in the Hsi–an Fu,[74] in Shensi; Wu Chou
in the Chin–hua Fu, in Chêkiang; Yo Chou
in Hunan; Shou Chou
in Kiangnan; and Hung Chou
, the modern Nan–ch´ang Fu, in Kiangsi, the district in which is Ching–tê Chên, afterwards the ceramic metropolis of China. Of these wares we have only the meagre information that the Yo Chou ware was of green (ch´ing) colour; the Shou Chou ware, yellow; and that the Hung Chou ware was a brownish colour,[75] and made the tea appear black. The Hung Chou factory is also named in the Ko ku yao lun,[76] which tells us that "vessels made at Hung Chou in Kiangsi are yellowish black in colour." A sixth factory, apparently of some reputation though not mentioned in the Ch´a Ching, is named in a poem by Tu Fu, president of the Board of Works,[77] in the T´ang dynasty, who says: "The ware (tz´ŭ) baked at Ta–yi is light but strong. It gives out, when struck, a sound like the plaintive note of the Chin–ch´êng jade. The white bowls of your Excellency surpass the frost and snow. In pity hasten to send one to the pavilion of my studies." Ta–yi was in the department of Ch´iung Chou, in Szechuan.
