Dear David,
I am writing to tell you something about the square dance in China. In the morning or after dinner, people, especially elderly women, will gather in squares to dance to popular music. More and more young people are also joining in now.
There are many reasons behind its popularity. First of all,China has made great progress in its social and economical development in the past decades, and people have more time and energy to enjoy themselves. Besides,doing the square dance is a good way for people to keep fit.
However, just as each coin has two sides,this kind of dance has also leads to some problems. For example, dancers play loud music and occupy lots of public places, which annoy many other people.Maybe square dancers need to make some changes.
Yours,
LiHua

亲爱的戴维，
我写信是要告诉你关于在中国广场舞的东西。在早上或晚饭后，人们，特别是老年妇女，将聚集在广场跳舞流行音乐。现在越来越多的年轻人也加入进来。
它的流行背后有许多原因。首先，中国在过去几十年的社会和经济发展取得了巨大进步，人们有更多的时间和精力去享受自己。此外，做广场舞是人们保持健康的好方法。
然而，正如每个硬币都有两面一样，这种舞蹈也导致了一些问题。例如，舞者大声地演奏音乐，占据了许多公共场所，这让许多人感到不安。
你的好朋友，
李华
