Liu Tze Long is a character in the Lilydale series.
Liu was born in Junk Bay, Hong Kong where he still lives in a public housing estate not far from this area. He was raised by his father who worked for a ship breaking company and often pulled double shifts. During these years, Liu would stay at the shipyard and help him dismantle obsolete ships for scrapping.
As the ship breaking business began to dwindle out, Liu and his father took some demolition jobs under the table. It all came to a stop when his father injured his back. Liu was 19 and couldn't support them both with his own income. Quickly crumbling under debts, he needed money fast.
With ample experience in demolition and mine disposal, he returned to Hong Kong to join the Explosive Ordnance Disposal Bureau. Soon after, he joined SDU to deal with Chemical, Biological, Radiological and Nuclear Terrorist threats.
He fell in an oil tank when scavenging an old ship when he was 10. Trying to break free, he ingested a significant amount of water seethed with toxins. Since the tank walls were ripped he managed to break free but not unscarred. Liu is highly resistant to physical hardships. He is one of the four recruits who were able to withstand the extendded version of SAS resistance to Interrorgation Program.
