Do you know why different animals or pests (害虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts (蝗虫). But birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is protecting themselves. Bears, tigers and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? An octopus (章鱼) can send out a kind of very black liquid when it faces danger. While the liquid spreads over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.

Do you know anyone born in the Year of the Tiger? What’s their personality like? Are they brave, strong and tenacious (坚韧的)? If so, then they are a typical “tiger”.
In Chinese culture, tigers are considered the king of all animals. They stand for power, energy and protection. Tigers are regarded as fearless animals, so that’s why in China you can see pictures of tigers on the walls of houses to keep away danger.
Tigers have an important cultural meaning not just in China, but across Asia. As they mostly live in Asia, for many people in the West, they have become a cultural symbol of Eastern countries and regions. For example, strong economies in the East—Singapore, South Korea, China’s Hong Kong and Taiwan—were called “The Four Asian Tigers”. In the book Life of Pi, Canadian writer Yann Martel chooses a Bengal tiger as the partner for the Indian boy Pion his adventure in the Pacific Ocean.
In the West, ▲ . A famous phrase is “eye of the tiger”, which means power and strength. In English, if you want someone to calm down, you can say to them, “Easy, tiger.”
Tigers are also one of my favourite animals. I first learned about the beauty of tigers as a child, while watching animal programs. If you ask my mom, she’ll tell you that my favourite toy was my toy tiger, which I have treasured dearly to this day. As an animal lover, I feel so sad that they are in danger and I want to help protect them.
Just as tigers serve as a symbol of protection in Chinese culture, we hope that in the Year of the Tiger more people can learn about tigers and help protect them.
