Hey kiddo, so have you ever heard of Hong Kong? It's a really cool city that some people live in. And do you know what Thailand is? It's a country where other people live.
Some of those people from Thailand have come to live in Hong Kong! They are called Thais in Hong Kong.
When they get there, they might need to find a place to live and a job to make money. And when they are out and about, they might speak a language called Thai to their friends or family. But when they are at work or school, they might also speak the language that other people in Hong Kong speak, which is usually either English or Chinese.
Just like you might have different toys and clothes than your friends, Thais in Hong Kong might have some different customs or traditions than other people in Hong Kong. But that's what makes us all unique and interesting!
