The Silk Road and the city Luoyang - an ancient mural in Mogao Grottoes in Dunhuang. Since about 2,000 years ago, Luoyang, the capital of the East Han Dynasty, became the destination in the east for the Silk Road. By the 4th century, Luoyang developed into an international metropolitan with three layers of city walls, 220 fenced residential zones and 600,000 populations, with numerous hotels catering visitors from overseas. Apart from peony planting which was the best in China, mulberry cultivation was also popular thus the booming of the production and trade of silk. #china #silkroad
