Dear Tom,
Very happy to have heard you. In your last e-mail, you asked me for the advices on how to travel casually in China. Now I’d like to share my opinion.
Nowadays, take China’s high-speed trains is a popular way to travel. Firstly, it’s fast and convenient. By the end of last year, the high-speed railways have been built in most of the cities in China, which could help people travel to different places fast than ever. Up to now, the high-speed railway network has covered the total of 22,000 kilometers. Secondly, it’s stable. In 2015, which a Swedish man videoed surprised the whole world. She erected(竖立) a coin on the windowsill or it stood for 8 minutes. How amazing! So, buddy, why not to have a try?
Yours,
Li Hua
