POP star Jacky Cheung pledges that he will get his first degree from the Open Learning Institute (OLI) before he retires. He made this commitment at the ''Towards a Learning Society'' concert recently. Cheung and Sally Yeh were both named honorary students of the institute, majoring in Business Computer and Western Literature, respectively, in the evening event co-organisedby RTHK and the OLI. The concert marked the end of the five-month campaign to promote the importance of life-long education and raising public awareness of distance learning. The Governor's wife, Mrs Lavender Patten, Secretary for Education and Manpower John Chan, and Director of Education Dominic Wong officiated at the opening ceremony, which was attended by about 2,500 OLI students, by unlocking the ''Treasure of Knowledge'' with the ''Keys of Wisdom''. The keys were passed in turn to Cheung and Yeh. Former Miss Hongkong Monica Chan and RTHK disc jockey Clarance Yang were the hosts. Other items included a piano performance by well-known Japanese pianist Yukie Nishimura and sketches by actor Kwong Chor-fai, Monica Chan, students of OLI and RTHK DJs. Students also teamed up with John Chan, Dominic Wong and Legislative Councillor Yeung Sum in some games and quizzes. Yeh and Cheung wrapped up the variety show in by singing ''The Greatest Love of All'', accompanied on the piano by Nishimura. The concert was broadcast live on RTHK Radio 1. The ''Towards a Learning Society'' campaign was officially launched last November. The campaign, which comprised roving exhibitions, quiz shows, weekly radio talks and plays, provided the public with a clearer picture of the role of the OLI.
