In summer holiday, Mr. Hung, Mrs. Chi and their children, Tuan and Hoa often go to the beach for two or three days. They usually go to Vung Tau in the South of Vietnam. They usually stay in a small house or flat by the sea, but sometimes they stay in a hotel. Last summer they went to Nha Trang. They stay at Ngoc Hoa hotel for three days. In the morning Tuan played soccer with his father on the beach, Hoa and her mother walked along the beach and built sandcastles. They visited Tri Nguyen Aquarium and saw different kinds of fish there. They bought a lot of souvenirs for their friends.
