China is very smart country. They accept nothing from others but give everything made by them to whole world. We also buy because all their goods are much cheaper than ours. I have stopped using amazon, ebay, flipkart, snapdeal since the day i came across aliexpress and have purchased so many goods from them.
In this way they are making their economy stronger. They dont even allow facebook and google in their country. Instead they use baidu and UC browser respectively.
