英语一个句子做后置定语修饰一个词是什么语法？求大神解答

Question

My family and I plan to travel there from May 1st to 7th, in which period we would like to visit most of the scenic spots and shopping centers.

we would like to visit most of the scenic spots and shopping centers.是修饰period吗？

Answer 1

My family and I plan to travel there from May 1st to 7th, in which period we would like to visit most of the scenic spots and shopping centers.
in which period we would like to visit most of the scenic spots and shopping centers非限制性定语从句，in which period指代前面的from May 1st to 7th：相当于in that period（在那期间）
分成两个句子：My family and I plan to travel there from May 1st to 7th. In/During that period we would like to visit most of the scenic spots and shopping centers.
可换成：during which period
又如：
t took two years for me to get better, during which time he spoon-fed me and did absolutely everything around the house.
我花了两年时间才好起来，在此其间他用勺子喂我进食，并承担全部的家务。

Answer 2

这里in which period可以直接用in which或者When来代替，都是引导的定语从句，修饰前面的1到7号，因为是一段时间，所以加了一个period

Answer 3

in which ...到句尾是非限定性定语从句，修饰前面的时间(五一假期)。

Answer 4

用句子做后置定语称作“定语从句”。定语从句由关系代词 that、who/whom、whose 或关系副词 when、where、why 引导。
