帮我看看这篇英语作文有什么问题吧~（单词拼写和语法）【书信】
Dear parents,
I miss you so,and hope everything goes well with you.Today I am writing to tell you something about my life here in Shenzhen.
As you know,I am so happy to visit Shenzhen again,great changes have taken place since my first visit 3 years ago.When mentioning Shenzhen,people never forget to speak of Huaqiang Road,it is a very busy commercial district,I often visit the IT digital shops there when I have spare time,sometimes I take a walk along the road in the morning at weekend； besides,there are many beautiful high-rise buildings there,which look very spectacular and gorgeous when the night approaches and streetlamps begin to light.
I am looking forward to hearing from you.
Best regards.
Yours sincerely
Kim
