Only a week after the $40 million Avenue of Stars was launched, workers were yesterday seen cleaning up some of the visibly stained handprints. Bits of chewing gum were also seen on handprints, including those of 1950s Cantonese opera diva Fong Yim-fun, and dirty stains were found on those of 1960s actress Li Lihua, known as the 'Eternal Beauty'. The Avenue of Stars Management company said it was unlikely that protective covers would be installed over the prints. Stephen Yuen, executive director of the company, said: 'Any protective equipment would have protruding parts and some visitors may trip over them.' He said a layer of wax had been put over the handprints for protection. 'We have the original moulds of the handprints and we can make new ones [when necessary].' To date, 34 of the 73 stars to be honoured in the avenue have had their handprints taken. Television mogul Sir Run Run Shaw, actors Chow Yun-fat and Stephen Chiau Sing-chi, and director Wong Kar-wai will soon provide their handprints.
