You could the subway from the Happy Valley to arrive at Shenzhen Luohu Port directly. Go through the port, you could take the train of KCR East Rail to arrive at Tsim Sha Tsui East, then please walk to Tsim Sha Tsui in 20 minutes.

ok...i little bit confuse here.
did we need to go to hung hom first or just take from east tsim sha tsui...because i come accross one map of MTR, lowu-east sha tsui-lowu (east rail line)

Hi, Ms ana, Actually the East Rail runs between Hung Hom and Lo Wu.Tsim Sha Tsui is not on this route. You should change to the West Rail Line when you arrive at Hung Homg and just one stop to Tsim Sha Tsui East. There are underground passage for you to walk to Tsim Sha Tsui Station. They are close to each other and with just a few minutes' walking (ten minutes I think).
