The book fair should be a healthy activity for families and teenagers.

But pseudo-models' photo books have been criticised for showing overly sexy photographs.

Some parents think these books will convey a negative message to their children.

Some people also believe the fair was more chaotic than usual this year because of the many fans hoping to catch a glimpse of the girls. It interferes with other visitors who want to buy books.

Many people have negative feelings about pseudo-models. These girls are not catwalk models, but merely show off their bodies in provocative poses and outfits.

But we cannot just blame these girls without looking at society and the importance people place on products like the photo books.

We need to change our attitude.

While book fairs should move with the times to attract customers, I don't believe causing so much controversy is the right approach.

Make your life even more enjoyable

We can all make changes to our lives to become even happier. I have some suggestions to help you enjoy life more.

Some people think their lives are fantastic, but others feel they have a tough time. How you react to events can affect the way you perceive life. People who enjoy life are usually optimistic about things that happen to them.

A lot of research has shown that laughing regularly can make you happier overall.

Finding substance and meaning in life can make you appreciate it more. For example, if you help others through voluntary work, or find hobbies that you really enjoy, your life will feel meaningful and you will be happier.

It's not difficult to live happily.

A healthy attitude towards money

Many teenagers have a twisted attitude towards money and material goods. This can have a negative effect on our development.

One of the most serious results of this attitude is the popularity of compensated dating.

In Hong Kong, many people enjoy a very high standard of living. It's perhaps natural that young people assume the more money they have, the happier they will be.

Girls sign up for compensated dating because they can earn money to buy the hottest new mobile phone or the coolest brand handbag.

These items are not really necessary. They are a luxury, and it is never worth risking your life for such things.

What we really need to pursue at our age is knowledge and friendship.

These last forever, and enhance our lives far more than belongings.

Happiness doesn't come from materialism, but from working hard to be a better person.
