It’s a crazy dream!Riding from Shanghai to London!Starting on March 5, Zheng Sheng spent 136 days travelling eleven countries and finally arrived in London on July 18.

Having studied maps for four months and borrowed（借） some money from friends, he left the company（公司） in Shanghai where he had worked for just a few months.

“I was very confident at the beginning, but after I left China, I felt a little worried that I might meet bad men,” he said. Luckily, the trip was a safe one. Zheng believes that the safest place to sleep is somewhere people don’t know about, so most of the time he slept in forests（森林）. He rode more than 100 km every day, but most of his food was just bread, as the food in Europe was too expensive. Later he learnt to add some cheese to the bread. Zheng didn’t tell his parents about the trip before he left for London, as he didn’t want them to worry. After he arrived home in Yunnan Province at the end of July, he finally told his mum about it.

“I’m very confident for the future,” he said, “because I know very well that everyone can do what they decide to do.”
