They were frequented visited by tourists and the locals during the Lunar New Year. Previously, they burnt joss sticks, tied joss paper (on which wrote their name, birth of date and wishes) to an orange then threw them up to hang in the trees. This was originally a custom of Taoist. It was said that your wish will become true if they do not fall down.
The higher they are, the more possible your wish will become true. The two trees perform their own functions: the big one is related to study, business, residence, wealth and health while the small one is relevant to children and marriage (It is a custom in China to pray for good fortune. The blessing is mainly held around festivals by a single person or in a group.
They mainly pray for good luck for their families, health, marriage, business, etc ).
This practice was discouraged by the authorities in 2005 because two people were injured during the visit. Instead, wooden racks are set up in place for the joss papers to be hung while a period of conservation is imposed to help these trees recover and flourish.
