Speaking about how things have improved for caravanning, he says that in 2015, the Traffic Management Bureau of the Public Security Ministry allowed travel trailers' to be on road in China, including highways.

"It's not a legal clause, but it's big progress for China's RVs industry. Now, you only need to get a special license for your trailer.

"In the early years, I had to explain to traffic police what a trailer is and argue with them that a trailer can be run on road. Now, they are not surprised to see them."

Explaining how caravanning works, he says RV lovers typically frequent places that have no water, electricity or toilets.

And when they get together, they obey an unwritten rule that each one carries his one's own chair and food.

Ge says that when he first went to camping, he felt relaxed after enjoying a barbecue, drinking and chatting.

Before that, he thought of camping of tedious.

"When I woke up by the lake the next day, I realized I wanted this kind of life," he says.

"You can take off your 'mask' and be yourself while hanging out with friends.

"You don't label them in accordance with their social status. "The only thing counts is that whether you share something in common," he says.

After that, he fell in love with camping and then started to go caravanning.

Now, domestic and overseas corporations are eyeing the Chinese market.

Zhu Jun, the vice-general manager of Beijing-based company RV International, which is the Chinese agent for Germany trailer brands Hobby and Fendt, says: "As more Chinese go for RVs, the imported brands are catering to the demands of Chinese customers."
