No country is perfect. We can learn from their advantages and improve our shortcomings.
It's just that the government personnel of every country are above the top and feel that their policies are fine and they don't know how to improve.
Everyone has a high degree of attention to China, and I often see the keyword "China" on forums. Why is this?
Right, no country is perfect, no country is clean and pure. Every country has their own bad things, there is no way there is a perfect, great, awesome country with no flaws. Especially, china has different system, which might be quite controversial for people, no freedom, but they offer an equality. US might offer freedom, but not equality. The reason why people often mention these two countries, and compare them is due to their power. We can't deny that China and US has the biggest power in financial, enough to suppress each other and affect other surrounding countries. However, I don't think both countries is perfect enough, they all have their own pro and cons.
