The absence of either would give you a big disadvantage.

IQ refers to the power of calculation, interpretation and problem-solving skills.

In this advanced era, such qualities are very important.

IQ helps compare people's abilities and identify the best.

EQ refers to our ability to control our emotions and co-operate with others.

Humans live as a group, not individuals so co-operation is crucial. A high EQ can improve efficiency and interpersonal relationships.

IQ and EQ cannot exist alone; they are interdependent or they will be of no use.

But it's hard for people to excel in both.

Mainland offers golden opportunity

I would like to express my opinion about the growing trend of studying on the mainland.

I believe that Hongkongers who study at a top mainland university have a bright future.

I visited Peking University over the summer holidays and it was a wonderful experience. The study tour, organised by the Hong Kong Girl Guides' Association, gave us a glimpse of university life on the mainland.

I hope to further my education at Peking University in future.

If I want to achieve my goal, I need to improve my English and Putonghua skills.

I'm surprised that the majority of young people here still look down on mainland students.

They think that China is a poor country and has failed to keep pace with the rapidly changing world.

But I don't think they can compete with mainland students.

Hong Kong's teenagers are addicted to computers and rely too much on their parents and domestic helpers.

Studying at a mainland university can help Hong Kong students enhance their national identity.

China is becoming stronger and more prosperous and many foreigners are keen to learn Putonghua.

Being a part of China, we should grab any opportunity to study in our motherland.

Exams still count

Exams help classify students according to their academic results.

This seems to be a good way of discovering the best talent in a competitive labour market.

But many employers complain that the staff they hire are not up to standard.

They say employees may be good in their studies, but their on-the-job performance is unsatisfactory.

Employers have suggested that academic results should not be the sole criteria in hiring new staff.

Their personality and other attributes should also be taken into account.

Exams may not be everything, but we still have to study hard to find a good job.

Japan should not cover up the truth

I'm writing in response to the article 'Japanese must listen to voices for truth' (SCMP, March 2).

The Chinese are very angry about the atrocities committed by the Japanese.

After I read the article, I felt the Japanese should be ashamed because they are trying to cover up the past.

Most importantly, history cannot be changed, no matter how they try.

In my opinion, it's better to face the facts and learn from history.

Then people will not repeat the same mistakes.

It is foolish for the Japanese to deny war-time brutality and refuse to listen to others.

This will only worsen relationships between Japan and its neighbours who suffered during the second world war.

Japanese school textbooks, magazines and newspapers are also trying to 'whitewash' the country's war-time atrocities.

For example, about 300,000 people were killed in the Nanjing Massacre, but Japan has yet to offer a full apology.

Compromise is crucial to easing tension between China and Japan.

Japanese Prime Minister Shinzo Abe should take steps to settle differences with the mainland.

Every country should bravely present the truth, and be honest and friendly towards its neighbours.

I'm sure that if Japan, as well as other countries, tells the truth, a lot of conflicts can be avoided.

Kwun Tong needs to be redeveloped

Kwun Tong is a rundown urban area in Hong Kong, so it should be redeveloped.

People there are facing serious environmental problems. They have to put up with air, noise and land pollution.

There are also many signs of urban decay, such as narrow streets and poorly maintained buildings.

Kwun Tong is a crowded place and the poor infrastructure is putting residents at risk.

Besides, a lot of the flats are above shops and there isn't much greenery.

The government should ensure that Kwun Tong residents have a better living environment.

Old and the new

Is it necessary for Hong Kong to sacrifice old buildings to ensure progress?

As a commercial city, Hong Kong has to keep up with the latest developments. But the city should also protect its heritage.

Reconstruction of urban areas may be feasible, but we also have to decide what should remain unchanged.

I do not agree with the idea that we must give up something to catch up with the rest of the world.

Old buildings need not be torn down. They could be turned into museums.

The government has enough resources, but not the will, to implement such projects.

We should not pay too much attention to money and technology. If all old buildings are torn down, Hong Kong will lose a vital part of its history.

Watch your step

In recent years, watching or uploading videos onto the internet has become a popular hobby.

It gives us a platform to develop our creativity. For example, we can add some background music, animation, and even special effects into short videos.

We can also share useful knowledge with other internet users and broaden our horizons. The sharing of videos can help improve people's behaviour, too.

Both celebrities and ordinary people would not want to be a laughing stock like 'Bus Uncle'.

Websites such as YouTube have helped police catch criminals.

This could lead to a reduction in the crime rate.

Uploading videos onto the internet is something that should be encouraged.
