Tourists have helped her hurry along and deliver dishes at restaurants during peak tourism season. Some even offered to hold travel team flags for her, she says.

Pan has taken Chinese tourists to most of the Southeast Asian countries, including Indonesia, Singapore, Malaysia and Thailand, as well as Japan, South Korea, the UK, Germany and Italy.

"About 90 percent of my guests are polite," she says.

Speaking of recent media reports of questionable tourist behavior, Pan believes that such publicity will help resolve the problem.

"Media exposure will bring uncivil conduct into public attention, which will definitely bring about good changes," she says.

She says that the worst scenario is that everyone turns a blind eye to bad behavior.

Pan called out two Chinese who jumped the line when going through security at Hangzhou airport.

"The two men immediately apologized and went back in line," she says

Her action also immediately made other loosely organized passengers form a line, she recalls.

"Some people are used to shouting each other's name from a distance and spitting in the agricultural field," Pan says of some people's habits.

It's a tour guide's duty to tell them local dos and don'ts when traveling outside, she says.

"I will keep reminding them of local rules, with savoir-faire."
