Hi, Mr rohit, if you have three days in Hong Kong, do not arrange that many places in one day. For you stay at Tsim Sha Tsui, you can so a lot of shopping for there are many shopping centers there. You can walk to the barbor area and Avenue of Star, watch the Symphony of LIghts at one night you walk around the harbor area. Apart from that you mentioned, you can also visit Polin Monastery, Big BUddha and Tai O fishing village in Lantau, or Wong Tai Sin Temple.
