For example, you can't loudly warn them against spitting in public, she says. "It's best to keep them from showing bad manners with a private word."

Pure admonition sometimes leads to ill feelings from customers and often fails to deliver desirable results. Pan's company puts popular shopping guidance and local taboos together on a list.

For example, it's considered being rude to touch a kid's head or step on a monk's shadow in Thailand, she explains.

Pan believes it's a process for Chinese tourists to bring their actions into line with international norms. She takes comforts in seeing that nowadays many kids would discourage their parents from littering on the streets. Students will simply explain that their teachers say it's not right to errant parents.

People will also line up to use public toilets at roadway stops, Pan says.

Pan is also an enthusiast for volunteer work. She has offered guide service for award-winners at the 8th China National Games of Disabled Persons in 2011.

Pan even began to learn sign language this year.

"I think sign language is like a foreign language, and our deaf friends will be more than happy to see us to communicate with them using simple gestures," Pan says.
