What should I do here just put all the things--they were.为什么

我们常说：
just put all the things there
就把所有东西都放那儿吧.
可见 是少地点状语的.
所以,定语从句就应该用where:
just put all the things (where they were)
常考还有一句：
For most of the people,Gulangyu is the place which called the paradise.
对大多数人来说,鼓浪屿才是那个被叫做天堂的地方.
For most of the people,Gulangyu is (where) called the paradise.
有时：the place which =where
