New rules from the China National Tourism Administration prohibit guides from steering their clients to illegal or immoral activities, such as gambling or drugs.

Guides are also prohibited from forcing clients to shop at businesses during a tour, or to charge extra money against a client’s wishes, through intimidation, restricting a person’s freedom or using physical force. Those who violate the rules will have their licenses revoked(吊销), and income generated through such misbehavior will be confiscated. In addition, violators will be fined between 2,000 and 20,000 yuan($300 to $3,000).

The administration said the quality of tour guides and the services they provide are key to the way the industry is perceived in China and abroad. Through the rules, which will take effect on Jan. 1st, the administration hopes to ensure healthy development of the domestic tourism market.

Mr. Wang, a professor of tourism administration at Beijing International Studies University, said the new rules act as a supplement to existing tourism law. “They elaborate tour guides’ responsibilities and will be very helpful for the national tourism administration in strengthening its governance of this group of professionals,” Wang said.

The 2001 regulations listed some prohibited behaviors, and guides who were found in violation would have points taken away from their annual scores. In 2015 and 2016, many media reports appeared about misbehaving tour guides at popular destinations. Guide services start with 10 points each year. Points are required to maintain a license, so if all 10 are lost, the guide service is shut down.

The new rules describe situations beyond what were in the 2001 regulations, and cover circumstances in which a tour guide would be in violation and punishments are laid out in detail, noting that some of the examples reflect situations that have been reported domestically in recent years. Forced shopping, verbal abuse of clients and even abandoning clients half way through a tour were among the misdeeds.
