I want to to the peak from hung hom station which is the fast and cheep way to reach

From the Hung Hom Station, you can easily find the CROSS HARBOUR TUNNEL/Cross Harbour Tunnel Toll Plaza on the Salisbury Road, so you can take the bus line 101 at that station to reach BANK OF CHINA TOWER/Bank of China Tower, Queensway Station. After you get off the bus, you can easily see the Peak Tram Lower Terminal, where you can take the peak tram to reach the top of the peak.
