Teacher: Now let's look at what you've done on your projects. Group one first, please.
Mi: OK. This is Angkor Wat in Cambodia. It's a temple complex, the largest religious monument in the world.
Teacher: Fantastic! When did people build it?
Mi: They built it in the 12th century. It's a World Heritage Site. Millions of visitors go there every year.
Teacher: Thank you. I wish I could go there one day too. And now group two, please.
Nam: Our project is about Dinh Bang Communal House in Bac Ninh Province - a national historic site. People were building it for 36 years, and it's about 300 years old!
Teacher: Great! It's quite magnificent! Now group three, please.
Lan: Well, this is Windsor Castle in England. It was built about a thousand years ago. It's been the home for about 40 English kings and queens.
Teacher: Yeah. It's the oldest and largest occupied castle in the world.
Mi & Nam: Amazing! So we need to preserve our heritage for future generations.
Teacher: Right. Thanks to preservation efforts, we know a lot about our history and life in the past.
