Dear Helen,
Hello,I am very happy to hear that you will come to visit my hometown,Dongguan . Welcome to come for a visit.
Its in the southeast of Guangdong in China . Its really a beautiful place. The weather is hot in summer and warm in winter .
Since 20 years ago ,Dongguan has few tall buildings and the roads were narrow . But now , Dongguan has developed rapidly .There are many tall buildings and more and more ring roads and subways appeared .
You can climb mountain or visit the beautiful parks . You also can have a picnic .I hope you will have a good time here.
Yours
Wangwei
亲爱的海伦，
您好，我很高兴地听到，你会来看望我的家乡，东莞。欢迎前来参观。
这是中国广东的东南部。这真是一个美丽的地方。这里的天气是夏季炎热和冬天温暖。
自从20年前，东莞只有几栋高楼并且道路是狭窄的。但现在，东莞发展迅速。有许多高楼大厦，越来越多的环城公路和地铁出现了。
你可以爬山，或参观美丽的公园。你也可以去野餐。我希望你在这里能有一个愉快的时间。
祝好！
王炜
