The happiest country in the world &in my mind.

      I am a college student, on the world's happiest country,I would like to say, although this year is Finland,I think it is China.

First of all, I think the popularity of online shopping, so that my life is very convenient, save a lot of time, and in China, Whether it is a taxi ride, buying a bottle of water by the roadside, or even paying a gas charge for water and electricity, it can be paid by mobile phone. In addition, China has "overtaken" all the way on highspeed rail, surpassing Japan, France, Germany and other highspeed rail powers that have developed for decades. It has become the world's longest mileage and most advanced highspeed rail power in the world. It has set a number of world records such as the highest operating speed, the lowest operating temperature, and so on. It has become a welldeserved "textbook" for highspeed rail in the world. China's highspeed rail is not only fast, but also stable.

  In short, I am happy and proud of it.
