I found the “tea trees” somewhere near Bukit Merah View, Singapore. There are tea bags on the trees, thus calling them “tea trees” are justifiable.
It is very convenient to throw everything outside your window, but it may cause inconvenience to other people. Please be considerate.
Looking on the bright side, if no one throws the tea bags onto the trees, then I would not have the chance to take the interesting pictures for you to view. Enjoy the pictures!
