In a tradition stretching back more than a century, visitors to the "wishing tree" in Lam Tsuen -- a village near the city's northern border -- come from all over the city and mainland China to take part.
Queues of hopefuls write their wishes on red pieces of paper, attach them to oranges and throw the fruit at a tree in the village square. If the orange lodges on a branch, the wish will come true -- or so the belief goes.
But that has not put off the crowds of annual visitors who started flocking to the tree Thursday and will do so for more than a week over the holiday period.
"I wished happiness and good health for my family. Everybody is looking for a good sign," Frank Fung, a 26-year old computer engineer, told AFP after he landed his wish on a tree branch with one throw.
Children, couples and the elderly, with many wearing bright red for good luck, threw their wishes, which cost HKD 25 (USD 3.22).
"It's my first time here, I think it's wonderful, I think it's traditional -- it's real Hong Kong," said Helen Friel, 27, from Ireland, who has worked in Hong Kong for three years as a teacher.
"I wished for good health and wealth for my family."
The tradition was started by Chinese fishermen who would write their wishes onto paper and throw them onto trees at the Lunar New Year, said Luke Lam, organiser of the festival, who was born in Lam Tsuen and has lived there most of his life.
"They would also leave red packets (containing money) attached to their wishes -- when I was little I opened the red pockets after they left," Lam said of the fishermen's offerings.
It is a custom to hand out red packets containing money -- known as lai see -- to relatives, friends and acquaintances during Chinese new year.
Originally attached to stones, the wishes were fixed to real oranges in the mid-1990s before the move to plastic fruit. In the past, wishing trees had also burned down as joss sticks were used to make offerings as well.
Over the years, the public adopted the fishermen's tradition of throwing wishes, spurred on by television soap operas which made it popular in the 1990s, said Lam, adding that the village sees more than 10,000 people a day during the Lunar New Year holidays.
"It's very universal to make a wish," Lam said.
