NAMING new streets in the rapidly developing New Territories can be mind-boggling - and the job is not made easier by deeply entrenched fung shui concerns among local villagers. Chinese superstition over the link between names and fortune is the main concern when the Government decides on a street name, according to the Survey and Mapping Office. Local residents are critical of how names sound and their meanings, said chief land surveyor Au Yeung Ping-kwong. A Sai Kung road originally named Tin Fat Road - the road of a field and Buddha - had to be changed to Tin Chau Road - field and continent - to avoid accusations of blasphemy. And the word 'sin' has to be avoided - because of its English meaning. That was the case with Yuen Sin Road in Tai Po, which was changed to Yuen Shin Road. Mr Au Yeung's office is responsible for naming new streets in the New Territories, while the Urban Council will take care of the urban area. He said there had been about 50 new streets in the New Territories last year and 69 so far this year. But there are no strict guidelines on street names. 'We always try to follow the tradition of the area. If a commonly-known name has existed for a new street among the residents, we'll try and make it official.' Mr Au Yeung said there were cases when commonly-known names were rejected because they were regarded as offensive.
