Hello my name is Long. Today, I would like to introduce about my neighbourhood. My neighbourhood is in Vinh Phuc province. It is noisy but clean and convenient. There are shops, schools, restaurants, hotels, markets and so on. The streets are busy and crowded during the day. I like restaurants best because the food there are very good. The people here are very friendly and helpful. I like living here so much because everything I need is only five minutes away.
