In the past, eligible young ladies will throw mandarin oranges on Chap Goh Mei into the river as a gesture of hope to get good husbands. Surprisingly, these traditions are still being practiced today :) Those who are interested can go to Esplanade, Penang to have a look :)
(side note : Fruits are expensive nowadays.. Shouldn't waste the fruits by throwing them into the river. More practical to just consume the fruits. Hahhaha... But to those who wish to participate, I have no objections as well.. But please don't throw rotten mandarins. And don't forget to write down your contact number, email address or blog address on the oranges. And good luck to the throwers and pickers).
