    Last Saturday I took bike trip to the nature park together with three of my friends in the breeze (微风), there we went for sighting. In the forest, we saw a number of plant and knew a lot about them. And then we go to a patch of grass that was full of wild flowers. We lay in the sun quietly, enjoyed the fresh air. The sight was very amazing that we didn't want to leave. We talked about our experiences happy and played several childhood games. Later, we had photos taken together and rode back to home.

    It was really an unforgettable weekend because they learned a lot about plants. With addition, we relaxed ourselves by enjoying the beauty of nature.
