Dear Robert,
There are four seasons in the year here—spring, summer, autumn, and winter. Summer is the hottest season. It often rains, sometimes quiet heavily. I often go swimming, sometimes in a lake near my home, and sometimes in the river, I enjoy it very much.
Autumn is a busy season. The days get shorter and the nights get longer. It is harvest time, and all the farmers are very busy. Often, we help them with the harvest.
The coldest season of the year is winter. I quite like it. Sometimes it snows, and the
land is covered with snow. Then we go skating.
Yours,
Wang Wei
