Life is not only about money
Some people think money is the most important thing in life. They say the rich are always at the top, while the poor are always at the bottom. If you have a lot of money, you can do what you want, they say. I don't think so.
You can't use money to 'buy' good health, friendship or love. When you have a good relationship, you will enjoy being with each other, and care about each other. Money has little to do with it.
Being very wealthy does not necessarily make you happy. You could be afraid that someone will cheat you out of your money. You could also be scared to make friends thinking that they are after your money.
Money is important but it's not what life is about. Remember, money can't bring you good health and happiness.

Public health should get priority
There's been a series of protests over the provincial government's plan to build incinerators across Guangdong. Some residents have demanded that the construction of a second incinerator near their neighbourhood be scrapped because of fears it would cause more cancer cases.
I think their concerns are reasonable, so officials should think twice before going ahead with the project.
A day earlier, a group of residents from another area - wearing surgical masks and mobilised by an internet forum posting - also demonstrated against the construction of an incinerator.
One demonstrator said they requested to meet officials at the city government headquarters and explain their concerns. But they were greeted by 80 police officers instead. Some residents were going to march to the provincial government office but they were blocked and told to leave.
I think the government should pay attention to public opinion. The construction of incinerators can pose a health hazard to the people.
Public health comes first.

Many young people admire celebrities and try to imitate their looks and behaviour. So it is very important that popular stars lead exemplary lives.
You may argue that their private lives are none of our business. Off the stage, they are just ordinary people like us and should be free to do whatever they like, you may say. I don't agree.
Nowadays, teenagers worship their idols so the rich and the famous should be more careful about what they do in public. They easily attract the paparazzi who are on the lookout for juicy stories and photographs.
Celebrities are role models for teenagers. So they should behave well and set a good example for others to follow.
Let's treasure every drop of water
Water is vital to all organisms in the world. Without water, all species will die out. The once-in-a-century drought in Yunnan province is a terrible disaster that threatens people's lives.
In Hong Kong, we have abundant water but so many of us waste it.
It is time for us to learn how to save water, save ourselves and save our world.
I have seen people using a washing machine to wash just two or three pieces of clothes. This is a waste of water and electricity. They should wait until their laundry basket is full before they switch on the washing machine.
We need to water our plants daily. For this, we can use water left over after washing rice, fruits and vegetables.
Also, we should take a short shower rather than a bath. And we should close the taps properly to prevent water leakage.
One small step by us is a giant leap for our world and our future!
