When was the compass invented by China introduced to Europe and popularized?

/kloc-in the 6th century, China's compass was introduced to Europe. This technology was quickly applied to the navigation industry, which promoted the opening of new routes. Through colonial plunder, a lot of wealth was plundered to Europe, which became one of the important sources of primitive accumulation of capital in early Europe. Since then, a series of changes have taken place, such as the commercial revolution and the price revolution. European capitalism has developed. This is why Europe is now more advanced.

China people look at Feng Shui with compasses, but they don't turn technology into productivity. This is the reason why China has fallen behind in modern times.
