A serial housebreaker with a colourful Chinese name has been jailed for four years and four months. The burglar, whose name means 'blowing a kiss at midnight', preyed on the occupants of housing estates. Ling Sun Yat-mun, 37, who pleaded guilty in the District Court to three counts of burglary, broke into three flats in housing estates between November 23 and December 9 last year. Formerly known as Tang Wing-cheung, he is believed to have adopted the fanciful name as his legal identity two years ago. He has some 14 previous convictions on burglary-related charges. The court was told that on November 23, Ling Sun entered a flat on the Oi Man Estate in Ho Man Tin with a spare key left by the occupant under an iron grille. He stole some keys and gold jewellery. Two weeks later, he broke into a flat on So Uk Estate in Cheung Sha Wan while the occupant was asleep. He made off with, among other things, a handbag and $1,500 in cash, without waking the occupant. Two days later he entered a flat on the Ka Wai Estate in Hunghom while the occupant was away, and stole jewellery.
