Today, Tony and I went to the countryside by the bus for the Strawberry-picking Festival. It starts at 8:00 in the morning. After the organizer introduced the rules of the festival, we led into the strawberry garden by some girls. While walking along the road, we saw beautiful flowers and heard birds sang. The air was much clean than that in the city when we live. During the festival, we enjoyed sweet strawberries or watched some exciting performances. At about 5:00pm, we had to say goodbye for the garden. Tony and I enjoyed us and hoped to visit there again. How an unforgettable experience!
