Two men who returned to a hero's welcome in Japan after travelling 20,000km on a shoestring will now promote tourism for Hong Kong. Tse Chiu-yan, 26, a Commercial Radio DJ nicknamed Superman, and Japanese actor Takashi Ito, 22, will try to sell local cuisine to the Japanese, who have been visiting in far fewer numbers. Tse said what he missed most about Hong Kong - apart from his parents and friends - was the food. 'During the journey, I described every detail of Chinese food to Takashi from fish balls, roasted pork and dai pai dong noodles to . . . so many,' said Tse. The duo, starting with just $6,500 between them, set off from Cape Town last January, travelling north through Africa, around the Mediterranean and into Eastern Europe before finishing their 11-month trip in Oslo. The odyssey, filmed by the Japanese TV station that organised the adventure, made the duo famous in Hong Kong and Japan. On several occasions, the pair ran out of money and did not eat for days until they were able to earn money by working. Tony Tse Sze-ming, general manager, marketing communications for the Hong Kong Tourist Association, hoped the two could help boost Japanese interest in visiting Hong Kong.
