Go on a trip to ShangHai 的英文作文?带翻译的

My friend went to Shanghai last Monday。 He could not understand their dialect。 But, they could speak Mandarin although ,sometimes, it was hard to understand their Mandarin。 My friend's last name was Wang。 His friend's last name was Huang。 But Shanghai people had the same pronunciation for Wang and Huang。 So, when they called my friends, my friends did not know who they were calling。 However, most time, they could understand each other very well with Mandarin。After my friend told me this story, I felt that it was so import for all of the Chinese people to have one languague in common。 Otherwise, we would not be able to travel too far。
