My parents live in the country. They keep a dog called Ah Fu. One day my parents went to work in the fields taking my little sister and Ah Fu along. While they were wokring, my sister walked to a river nearby. Ah Fu followed her there. She was trying to pick a flower when she fell into the river. Ah Fu barked and jumped into the water immediately . 　When my parents heard Ah Fu barking they ran to the river. They saw Ah Fu swimming towards the bank carrying my little sister. My parents praised Ah Fu warmly. It was our brave Ah Fu who had saved my little sister.
