Princess Cruises has tailored the entertainment for Chinese guests so that it is easy for them to understand and appreciate it, Kaufman says.

The shows include both English and Mandarin. It also uses advanced technology in shows, such as 3-D graphics to enhance the visual effects.

Other celebrities on board include former Olympic champion diver Tian Liang, his wife－singer Ye Yiqian－and their son and daughter.

"Our children love the ocean. So, when they are having fun in the Youth and Teen Centers, my wife and I can take time to enjoy ourselves," says Tian.

"The Chinese are very active and want to engage in the activities on board," Kaufman says. "It is important for them to travel together as a family unit. That is why we provide activities that appeal to different generations.

"Cruising is a fantastic way not only to see the world but also be with your family and friends. If you want to enjoy a beautiful beach, but the other person wants to join the activities on board, each one could do his own thing and then have dinner together."

Kaufman is confident about the future of China's cruise business over the long term.

In January, the China Cruise & Yacht Industry Association said that the number of outbound cruise passengers reached a record 2.12 million in 2016, up 91 percent over 2015. Separately, the number of overseas cruise guests visiting China increased 8 percent to 138,700 last year.

Shanghai, Tianjin and Guangzhou were the top three ports for inbound and outbound travelers.

Beijinger Qi Ming, who took a cruise overseas with his family last summer, says: "The voyage was very relaxing, suitable for kids and the elderly. We don't have to pack and unpack or carry heavy luggage.

"And everyone can find their favorite activities on board."

If his 2-year-old daughter fell asleep, they could simply carry her to the stateroom.

"The crew was professional and loved to interact with kids," the 31-year-old says. "Also, the grandparents could take a rest whenever they were tired."
