See the point? This is typical Chinese bragging about their achievement. If some how, some day they did pass the U.S. and Japan, you will see load of Chinese on internet spamming similar posts "Yeh I am top of the world, you westerners decline, inferior...etc."
What funny these Chinese never think, when they compare Vietnam with China? One country with limited fund and one country with massive fund, tax of 1.3 billions people. What Vietnam lack of is fund. If I am Chinese I will be shame of my country of 1.3 billions people and tax but far behind Japan a country of 90 million, and U.S. 300 millions peopole.
See we Viet ever compare us with Cambodia? a country with 16 millions? No, we strike to be like Japan we compare ourself with Japan and see how lag us behind. We don't do monkey jump up and down on internet whenever something come out of country. Sure we might share our achievement but we don't do "monkey comparison" like many Chinese does, boasting, bragging, make it like world greatest invention and that so superior, other inferior.
And here how we answer to your "greatest invention". That is only use by Chinese. So keep doing good job boasting. To this point all your tech are just copy cat and use widely by 1.3 billion Chinese, nothing break through yet.
For Chinese tech companies overseas, China is a toxic brand
Tell me, how many of China's technological milestones (see below) can Vietnam match? Since you Viets are living in the Stone Age, why should any Chinese here care about the opinion of a primitive Viet? You Viets are not a technological people. You Viets are merely a bunch of non-industrialized backward primitives with big mouths.
