Last Thursday we go to Mianshan Mountain for our autumn outing.We got the foot of the mountain at 9 am. Following the long path,they began to climb.After some time,we were all tiring.We had a very shortly rest and moved on.At last,we succeeded in getting to the top,on which we kept laughing and jump.It was seemed that we were the happiest people in the world.We took some photo there,and then sat down but had something to eat.At 3 pm, we began to go down.It was a interesting and unforgettable day and all of us wished the autumn of our country would be with us forever.
