It doesn't matter if you took a shot on a crowdy street you still have to own a model release agreed and signed by each of your subjects.
即使你是对着街上的人群拍照也不行，你必须拥有每一个主体的签名授权。

Oneday, I went to work by bus as usual, there were so many people on the bus, so it was very crowdy and there was no available seat left, even if I can not find a place to stand.
