The legality of the villagers' so-called right is the crux of the matter. Our secretary for justice has done a disservice to Hong Kong by the continual avoidance of this issue. In Hong Kong, we are proud of our rule of law.

While our officials and politicians have timidly failed to grasp this thorny matter, I am confident that the judiciary will soon clarify the legitimacy of the villagers' claimed "right".

Your report states that the indigenous plaintiff has lived in the village for more than 60 years, so this should be an excellent "test case". Such a ruling should be the departure point for a long-term and long-overdue solution to this irksome issue.

Using figures from the Hong Kong government and Civic Exchange, there are as many as 800,000 men worldwide who New Territories village heads would say are indigenous villagers.

Using Hong Kong demographics, roughly 8,800 of those turn 18 each year and become entitled to land to build a new house.

At 40 houses per hectare, that would require roughly 220 hectares a year. Hong Kong has 730 square kilometres (73,000 hectares) of woodland, shrubland, grassland and wetland; that is enough for 331 years of these rights, if we assume every hectare is suitable.

So by the year 2344 all open space in Hong Kong would be required to honour the 1972 policy - clearly a ridiculous situation. Taking a really long view, in 35,000 years the whole of Guangdong province would be filled as well.

How much of Hong Kong's open space will be sacrificed to the unsustainable small-house policy before it is cancelled?

Gordon Wu Ying-sheung laments the recent situation with argumentative politics and the government's intervention into the property market, and how this may affect future investment.

This is a bit rich coming from a dominant property tycoon, because it has been the relentless pursuit of maximum profit by developers that has been the root of the political polarisation of Hong Kong society. While fat-cat developers' property prices have skyrocketed more than a million people have fallen into poverty, and the wealth gap widens remorselessly.

We have no money and no sex; little wonder that Hong Kong's fertility rate is so low and that we have an ageing crisis

Hong Kong used to be a place of thriving optimism and opportunity, but developer aggression and extreme property costs have radically changed this. Hopewell Holdings' chairman should consider that, for many people, life in Hong Kong now appears without hope.

We have a solution to Occupy Central.

As if bricks and mortar are all we need for a satisfactory and fulfilling human existence.

Last month a UN meeting of world leaders was held to discuss the plight of the disabled.

I believe that welcoming the disabled into the community helps to strengthen social cohesion and to uproot social exclusion.

Often, people with disabilities suffer from a lack of access to education, health care, and social support. Discrimination also makes them feel isolated in society and unable to live in normal ways.

If more enterprises hired disabled people and offered them training, the companies would be fulfilling their corporate social responsibility. Governments also must act by providing disabled citizens with adequate subsidies for things that are essential to their lives, such as equipment they need to ensure mobility.

Such expenditure should not be seen as a waste of resources, as it is being used to help a minority that always appears to be suffering in silence.

If we all work to help the disabled integrate into society, then we will see fewer social problems and greater harmony within a community.

You often hear the term sustainable development; however, sustainable social development is something that is often neglected, or at least, aspects of it.

We talk about the importance of balancing the needs of the environment and the economy, but rarely do we look at the needs of the minorities living in our society.

As was mentioned at the UN meeting, future sustainable development goals in countries should include the needs of the disabled. As I said, we need to fight discrimination, encourage integration for the disabled and improve their living standards. They must be seen as part of our community's intangible assets.

All citizens have a role to play in this regard as individuals in society and in the global village, if we are to ensure greater global harmony.

It is all about collaboration and alleviating the state of social exclusion that is felt by so many disabled people.

There has been a heated debate about students who copied passages from the internet without citations for the Chinese-language school-based assessment.

Some people have argued that it was cruel for them to have their scores invalidated, because it would jeopardise their chances of getting a place at a university.

I think the Hong Kong Examinations and Assessment Authority (HKEAA) took the correct decision.

Copying from the internet is no different from cheating in an exam, because marks which are awarded for the school-based assessment are counted towards the final examination result.

Secondly, the whole point of the school-based assessment project is to illustrate what students have learned during their study period.

If they have copied material, that is no indication of what they have actually understood about the subject. It makes the whole assessment process pointless.

If youngsters were able to get away with copying material in school, how would they cope once they got a place at a university where such practices are completely taboo?

People who do such a thing are simply not suitable candidates for a tertiary institution.

The HKEAA simply had no choice but to invalidate the students' scores.

Tsoi Huen, Ma On Shan

She totally ignored the points I made. That the No 26 bus in the morning now operates more frequently is not in dispute.

For simple clarification, let me repeat, that from around 11am onwards, for the residents of Lai Tak Tsuen/Lower Tai Hang, the service to Central, with the cancellation of the 23A and 23B buses, has deteriorated by about 30 per cent.

On Sunday (another point conveniently ignored by Ms Liu), when the No 26 reverts to run at its usual 20-minute intervals, and of course, with the absence of the 23A and 23B, the service to Central has deteriorated by about 50 per cent.

If Ms Liu replies to this letter, I would like her to confirm that, as I have said, the bus service has deteriorated in this area.

If she disagrees, then I would like her to explain how this is the case.

To trot out that hackneyed phrase "We are monitoring the service" is just corporate speak and adds nothing to the already poor service.
