相思树
While climbing Li Jian San (力健山) which has similar treks like S'pore's Bukit Timah Hill, as I was just concentrating on the climbing and catching my breath, I didn't really realise the beauty of the place till I relook at some of the pictures taken of the beautiful surrounding sky and trees. :-)
Oh, there are 2 rest stops at top of the hill whereby you could have a good meal to regain your energy :-P
