Their profits come from discounts offered by airlines and hotels, yet prices they offer to clients are always reasonable, which can be discounted further.

It also provides tailor-made plans for visitors who prefer the road less traveled by.

"So far, there has been no itinerary that has been exactly the same for the groups I have received," said Kuang Jiangnan, a private travel butler at Planet Travel.

"Each group has different requirements due to time limits, budget or even energy," she said.
