Undecided questions
if you are foreigner in china, then what is best suggestion for your summer holiday plannings?

When I was in China I went with a study group and we had a tour guide. Most tour groups follow a similar pattern of landing in Shanghai, then flying to Beijing, visiting The Great wall of China, The Forbidden City, the Summer palace etc. You can also go to Xian to see the Terracotta Warriors. There are also a lot of lakes and gardens.

I would like to stay in a big city, Shanghai or Peking

GO TO THE BEACH OF DALIAN OR BEIDAIHE。

Make chinese friends as more as possible.Go to swimming in the sea,and eat seafood.
