Jenny Yuen Chun-ni, principal of the Lamma Primary School (pictured) said this week she was still facing opposition from staff loyal to sacked supervisor Chau Kim-hung who tried to oust her last term. She claimed the school's computer system and Web pages had been sabotaged and said administration software had gone missing. She and Education Department officials are urging staff to put the conflict behind them. 'We now need to trust, to understand and work together. There is so much that needs to be done.' Ms Yuen said staff had blamed those who had left the school for the computer problems. Alan Tsang Chiu-kit, the teacher in charge of the computers, said he was not responsible for the problem.
