BEIJING (AP)-The government is teaching the people "the right way to spit." A college teaches students the right way to sit. Two years before holding the Olympic Games, people across Beijing are on and all-out drive to mind their behavior. Visitors are often surprised to see people in China spit phlegm onto the ground. Changing all that before the 2008 Summer Games is "important in providing a cultural and historical legacy to the world for China," said Beijing city official Zhang Huiguang. "We will work with newspapers, radio stations, TV stations, the Internet and mobile telephones to teach people the right way to spit, said Zhang. Zhang said her office is organizing a "behavioral training" activity that teaches people to line up for buses and turning off mobile phones during meetings. But spitting is the most serious problem. "You have to spit into a piece of paper or a bag, and then put it into a dustbin," she explained. Zhang said her office has organized a small group of volunteers who are going to Beijing's streets to hand out small "spit bags". "Public spitters already face fines up to 50 yuan (about $ 7 Cdn)," Zhang said. Others are taking a softer way. Lu-chin was born near Beijing, married an American and spent 10 years in the U.S. She said her heart sank when she and her family returned to live in her homeland and she saw the spitting, littering and cutting in line. It caused her to start the Pride Institute, a private group that showing the great pleasure of being more polite. "I'm trying to wake up a sense of decency. I know it's there. I saw our beautiful scenery covered with plastic bags. Sometimes I think I'm the first one to see this and say, 'Why do you treat our country like a dustbin?' I'm just trying to wake them up and show them they can stop the bad behavior." Still others are trying to improve things in a far more traditional way. "All of China is looking forward to the Olympics," said Zhang Hui, head of training at the Beijing Courtesy College. "It's really important to improve courtesy before the Games", Zhang said. "Everyone knows how to walk, stand and sit," she said. "But we teach them how to do it in a good way." That means things like sitting, back straight, on the "front one-third" of a chair, she said, "Women sit with their knees and feet together. Men may sit with their feet slightly apart. If you cross your legs, you keep the toe of your lifted foot pointing downward." "Every day we teach the students about Confucius and Laozi. Every country has a basis for its culture." she said. "Confucius and Laozi are our country's basis."
