please suggest sightseeing for 2days in Hong Kong

Well, hereunder is my simple suggestion:
Day 1: Go to the Ngong Ping 360 for the nice scenery and Giant Buddha. After that, go to the Disneyland Resort for fun. There is night firework in the resort, which should not be missed.
Day 2: Go to the peak in the morning for sightseeing. After that, go to Tsim Sha Tsui (Avenue of Stars for relaxation). If you are interested, go to the Ladies' Street for shopping. If time is left at night, I suggest you have fun at the Temple Street Night Market.
