Khu phố em nằm bên cạnh trung tâm dịch vụ thương mại nên lúc nào cũng nhộn nhịp và đông vui,Từ tờ mờ sáng, sau một giấc ngủ dài, phố xá như bừng tỉnh dậy Các dãy nhà cao tầng hai bên đường đứng sừng sững như thách đô với đất trời Những cánh cửa sắt khổng lồ như một lá chắn từ từ được xếp lại đẻ lộ ra bén trong là những gian hàng mua bán. Nơi đây bày bán bàn ghế, chỗ kia là gian hàng may mặc, chỗ nọ là cửa hàng bách hóa… Gần như nhà nào cũng trở thảnh cửa tiệm buôn bán. Thỉnh thoảng mới xen vào là một gian nhà để ở.Ông mặt trời bắt đầu hé, những tia nắng dịu dàng chiếu xuống khu phố chợ, Những tia nắng tuy với màu sắc yếu ớt nhưng cũng xóa dần được bóng đêm. Và đường phố xuất hiện bóng người. Những hàng cây trồng ven đường như cố phô sắc nên vươn những cành lá xanh um còn đọng sương đêm. Một làn gió nhẹ thổi qua, chúng khẽ lay động vẫy tay chào một ngày mới. Từ trong các hẻm nhỏ, vài chiếc xe ba gác ì ạch chở hàng ra chợ. Xe nào xe nấy đều được chất cao hàng hóa… Trên lề đường khách bộ hành thong thả bước chân chầm chậm như đang hít thở không khí trong lành của buổi ban mai. Rẽ sang tay trái là một dãy nhà trệt, cổ xưa có lối kiến trúc giống nhau. Đây là khu dân cư nên sinh hoạt có vẻ muộn màng hơn. Nhà nào cũng có cửa rào, có trồng hoa trước sân hoặc trồng những cây che bóng mát như cây mận, cây trứng cá… để vào mùa hè làm giảm bớt sức nóng gáy gắt của ông mặt trời. So với các dãy phố khác, nơi đây yên tĩnh hơn.

I have just returned from a 1-week holiday with my friends in Da Nang and Quang Ngai. We stayed most of the time in Da Nang. Then we spent the last few nights in a very picturesque and historic place called Hoi An Old Town. We had such a relaxing time on our holiday. We enjoyed some wonderful local food. It’s really delicious. The activities we enjoyed on holiday were walking, swimming and go out at night. The water is so fresh and clean, and the temperature is just refreshing – not too hot and not too cold. We went hiking in the mountains nearly for some days, which was very good for our fitness. I really enjoyed this holiday. I loved the fresh air and the scenery, and of course the food. I will certainly be going back there another year, as I think it’s one of my favourite parts of the world.
