I think the new medium-of-instruction policy will worsen the labelling effect on students. Some parents will still push their children to study at a class using English. So for those who remain at schools teaching in Chinese, things will get much worse. Parents and students are always striving to study at English medium-of-instruction schools. Most of the parents think these schools are prestigious and they tend to regard schools that teach in Chinese as inferior. But when parents choose a school for their children, they should take into account their ability. I think schools should put students with good and poor English together to study. This would remove the labelling effect. As a father of a pupil at secondary school, I prefer to choose a school that fits the ability of my child. I would choose the school according to the ability of my daughter. I would not force my daughter to study at a school that teaches in English. It is not a good policy to separate schools like this. The mother-tongue policy is a failure in many respects. Students who are forced to study in English may find it difficult because they do not have the language ability, and they find it hard to catch up. On the other hand, those pupils at Chinese-language schools will lose the opportunity to learn English, which will lead to a decline in English proficiency. Yet despite this, the education minister, Michael Suen Ming-yeung, says the government will earmark HK$980 million in the next five years to implement 'fine-tuning' measures. I also think the new medium-of-instruction policy will increase the workload of teachers, as they may have to prepare teaching materials in both languages. Also, now is not the right time to implement the medium-of-instruction policy, as the new academic structure for senior secondary education will be implemented this year. These policies are new to pupils, schools and parents. I fear there will be chaos. One of the 21 most wanted Tiananmen Square protesters, Xiong Yan , passed through immigration at Chek Lap Kok airport and stepped on to Chinese soil for the first time in 17 years - flying into Hong Kong, the city through which he fled to the United States in 1992. He faced no questions from immigration staff. I was surprised by this. I don't know how he could enter Hong Kong so smoothly. But Jens Galschiot, the Danish sculptor and activist, was refused entry to Hong Kong after being questioned by the immigration authorities for five hours. I think the entry ban was related to politics. People's minds become more mature as time goes by. More people want political rights. I think it is better for a place to develop economically and politically at the same time. The police said a four-year-old boy was stabbed to death by a man wielding a knife in Sham Shui Po. I think the government lacks resources to back up its policy of getting mental patients back into the community. There is a lack of staff to follow up each patient. I think the government should hire more staff and increase the number of hospital beds for mental patients. We should not be afraid. We should help them integrate into the community. Two girls aged 13 and 15 were arrested and appeared in court on suspicion of mugging a taxi driver at knifepoint, and robbing him of HK$660 and a mobile phone. I think we should raise concerns on juvenile problems. Youngsters are too materialistic and are easily influenced by their peers. It is easy to go bad but it is difficult to turn good again. If a child is led astray, parents will obviously be upset. But I think family background can explain a lot. If a child has grown up in a single-parent family, it may be easy for him to be led astray. I think the installation of surveillance cameras in the cabs can help to protect us from such crimes. When someone wants to commit a crime, he or she would dare not do this knowing that a camera was recording every action.
