In the eyes of many young people, the widely used red, white and blue plastic carrier bags are only for grandpas and grandmas. However, students from SKH Tsoi Kung Po Secondary School (TKP) have drawn a series of murals to tell others that there is a larger meaning behind the coloured bags. 'It is the spirit of original creativity,' said the Form Four student Ng Kwok-fong, 15. 'Although it is simply just a plastic bag, it was created by Hongkongers. It has become one of the memorable icons of Hong Kong.' The Heritage Museum in Sha Tin is hosting an exhibition called Building Hong Kong - red-white-blue until April 18. Besides having more than 100 works by local artists, some contributions are from students as well. Thirteen TKP Form Four students' drawings are showcased in the exhibition, making the whole school very excited. In order to further promote the merits of art to students in other forms, the school invited more than 60 Form Four art students to draw murals along the stairs in the school. They worked very hard on the murals. Some of them stayed after school or went back on Saturday in the hope of finishing the project they named space4U. After three weeks of toil they finally completed nine murals in the school. Parents and guests were invited to see their masterpieces on speech day this month and the headmaster formally opened space4U at the same ceremony. Kwok-fong hopes the murals will persuade the other students to reflect on the importance of creativity. 'Previous generations have created so many things for us,' she said. 'We hope these murals highlight this message and encourage others to continue doing so.' On top of the main theme of red-white-blue the students also drew various local icons, such as the Star Ferry, double-decker buses, nai cha (milk tea), fish balls and the cartoon character McDull. Art teacher Margaret Yeung Kwok-fan said it was good to let students draw pictures everywhere. 'It makes the school more vivid,' she said. 'Students seldom go to art exhibitions. This way, the whole school seems to be changed into a large exhibition centre, which may boost the students' interest in visiting more public exhibitions after school hours.' Ms Yeung also emphasised that art should not be limited by space. The school is going to make more space available for the students to draw murals - including ceilings, floors and classrooms.
