There are four seasons in a year.
一年有四季。

Let us start from winter. Of course the snow is the symbol of the winter. It is the snowflakes, flying in the wind. The symbol of spring is the green colour coming into the sight. That is the grass. Broad and large leaves of the maize may be the symbol of summer. At last, the yellow leaves,falling down from the trees, means the autumn arrives.
让我们从冬季开始。当然雪是冬天的象征。它是那在风中飞舞的雪花。春季的象征是进入人们视野的绿色，那就是草儿。而又宽又大的玉米叶，可以作为夏季的象征。最后，从树上落下的黄叶，就一味着秋天的到来。
