The online show, On the Road, follows the adventures of a couple who stepped out of their comfort zone. Wang Kaihao reports.

Many people would probably expect that 40-year-old Zhang Xinyu and his 38-year-old wife, Liang Hong－having earned nearly 100 million yuan ($14.8 million) and owning nine apartments in Beijing－would be happy to live a comfortable life.

However, being comfortable is the last thing the couple wanted.

"I forgot how to be happy," Zhang recalls, when explaining their motivation for setting off on a round-the-world journey about a decade ago. "I thought, 'What if we changed our lifestyle?'"

So the couple decided to travel around the world－but in an adventurous way.

After taking five years to get the training they wanted－which included getting a pilot's license to fly helicopters, and diving and sailing certificates－they set off.

From a refugee camp in Somalia to Chernobyl, the couple's itinerary avoided the conventional tourist destinations.

In Russia's Oymyakon, which is said to be the coldest inhabited place in the world, Zhang warmed Liang's heart by proposing to her in 2013.

The couple then spent one and a half years sailing a boat to more than 20 countries and finally reached Antarctica, where they held their wedding in 2014.

They visited many places during this voyage, including an abandoned air base on Attu Island in Alaska, and Simushir, an uninhabited island in the Kuril Islands, which once housed one of the former Soviet Union's nuclear submarine bases.
