An unlicensed tour guide was jailed for two weeks yesterday for using the identity of a licensed guide with the same surname to get a job with a travel agency. Cheng Hok-kong, 48, was also fined HK$12,000 - the amount she earned with the fake identity. Magistrate Jonathan Wong Kwok-ho said the offence had harmed the interests of the travellers and tarnished the image of Hong Kong. "Tour guides need to attend first aid training - which means their responsibility is heavy," Wong said, adding that the requirement was much "higher than just passing a licensing examination". Kowloon City Court had earlier heard that Chen Youming, a retired national table tennis player, collapsed after arguing with Cheng over an alleged forced shopping trip. Chen was later found to have died from a heart attack. Chen's daughter went on to blame her father's death on the tour guide's alleged rude and unreasonable attitude. The court heard that Cheng used a phone message to lie her way into the tour job when Win's Travel Agency required her to provide her full name and licence number. She did not offer any other details and the message simply read "Cheng Ying-lai TG09000". Using the bogus identity, Cheng took a group of mainland tourists to a jewellery shop in Hung Hom on May 22, 2010. The retired athlete was one of Cheng's clients. Cheng led 20 tours between April 9 and May 22, 2010, and was never asked to provide any documentation to prove her identity, the court heard. Lawyer Olivia Tsang, for Cheng, said her client was not aware her offence "was so wrong in law" when she committed it. She said Cheng's lack of awareness was largely due to her education level. Joseph Tung Yao-chung, head of the Travel Industry Council, criticised the agency for failing to discover the fraud. "It is impossible that the agency did not check the details of its employees," he said. "Basically, every employer has to carry out pre-employment checks." The agency has been stripped of its council membership for a year. The council has since tightened rules regarding what travel agencies, tour guides and shops can and cannot do with inbound tour groups. Itineraries must also state that guides cannot force visitors to buy anything or stay inside shops. On October 1, the mainland authorities will bar travel agencies from using low tour prices to entice mainlanders to join the forced shopping trips.
