Bond，Bangkok，Thailand	You can find many wonderful things that we don't have in Thailand.We don't have Alipay or other online payment apps with which I can go shopping without stepping out of the doors.If only I could bring them back to my country！

Justin，Bucharest，Romania	I'm from Romania.China is really a great country and its high­speed railways are very fast，convenient and tidy.It takes me only 6 hours from Beijing to Shanghai by train.It saves a lot of time and it's cheaper than airplane.I wish we would have high­speed railways in our country someday.
