Shen Fuwei, Cultural flow between China and the outside world, p.116-120, citing the C3rd Guang Zhi on the maritime 'glass route' from Rome via India, Sri Lanka and Cambodia to China, The Periplus of the Erythraean Sea on the export of 'crude glass' to the East, and Wei Shu (History of the Wei dynasty) on the Indian technology transfer to Pingcheng (Datong).
Even the knowhow was eventually lost, but a separate glass industry later developed in the north, with assistance from India during the reign of Wei emperor Shizu (424-452 CE).
111 BCE: Wudi, who had already conquered Zhejiang and Fujian and moved their inhabitants inland, defeated and divided the Nanyue kingdom (which had covered modern Guangdong, Guanxi, and north Vietnam).
