人山人海
* a sea of people
* huge crowds of people
* a sea of faces
The square was a sea of people .
广场上人山人海 。
During the festival period , the park opens free .
What a busy place with huge crowds of people gathering there .
节日期间,这个公园免费开放,真山人海,好不热闹。
A ：How many people participated in the grand ceremony ？
有多少人参加那场盛大的仪式 ？
B ：Believe it or not，there was a sea of people .
信不信由你，人山人海 。
