My parents live in the country. They keep a dog calling Ah Fu. One day my parent went to work in the fields taken my little sister and Ah Fu along. While they working, my sister walked to the river. Ah Fu follow her there. She was trying to pick a flower while she fell into the river. Ah Fu barked and jumped into the water immediate. When my parents heard Ah Fu barking, they ran to the river.
