The federation, in a poll of more than 400 mainland tourists in November and December, found that nearly half were unaware of major historical landmarks on Hong Kong Island.
Lawmaker Kwok Wai-keung said travellers need a new mobile app to tell them where to go.
“As we know, tourism is a core industry of Hong Kong, so we have to put more information on the internet and let people know more about our culture,” he told RTHK.
“The one-stop platform should provide more information and also some transportation methods so that [tourists] can have a walk around parts of the city and try the local food.”
Noting that 80 percent of respondents would visit a place because of a book, the federation suggested developing creative themed tours based on literary heritage.
It also urged the government to better preserve local heritage, including neon signs and traditional shops.
