At an apartment block in Phuoc Long B Ward of Thu Duc City, a group of workers are tasked with cleaning the windows of more than 600 apartments. Standing on the roof of the 17-storey building, Cai Bao Thanh in a black T-shirt is about to tie the rope to some pillars to swing downstairs and start work. The ropes can bear a load of 2,000 kilograms.
"This is a very important job that requires high concentration. Only a small mistake could see you pay a heavy price," said the 26-year-old man.
The year end is the busiest time for window cleaners as many high-rise buildings and apartments in HCMC enjoy a spruce up in celebration of Tet, Vietnam's biggest and most important holiday that peaks on Feb. 12 this year.
