China's goods are very competitive all over the world, even monopolized. China in the Ming Dynasty had a very strong commodity manufacturing capacity, which could manufacture all kinds of commodities. Because of thousands of years of technology accumulation, the quality of goods in China is good, and the labor cost is very low, resulting in low commodity prices, which can be called good quality and low price.
At the same time, China has a special monopoly position in the manufacturing technology and production technology of many commodities. According to the data, as far as textile production is concerned, China is the origin of bast fiber, and has accumulated rich production technologies for more than 1000 years. The bleaching technologies of bast fiber such as "semi-soaking and semi-drying" and sulfur fumigation were at the world's leading level at that time. The products made of raw silk in China can withstand the sea breeze and do not change color. The style, weaving method, pattern design and printing and dyeing technology of European silk products are all influenced and inspired by China. What's more, it was not until 1690 that better quality flax was woven in Britain.
Foreign businessmen are full of admiration for silk from China. "All kinds of silk goods shipped from China, the most popular is white, as white as snow. No product in Europe can compare with China's silk. " . Look at that. That's great. The high quality and low price of goods is an important reason for China's trade surplus with Europe 100. Of course, it is also the decisive factor that Zheng He and his descendants got a lot of silver.
