in which 等于where,那on which等于where吗?

关系副词都等于一个适当的介词＋which,在从句中作状语
When=in/at/on/…+which;
Where=in/at/on/…+which;
Why=for /…+which
1.Do you still remember the day when(on which) we went to visit the museum together?
2.This is the factory where(in which)my father once worked.
3.This is the reason why(for which) he was late.

不能这样乱等于的.要看具体语境..
in which和where都是壮语,在从句中..inon which可以代替where 指代从句中的地点

定语从句中
介词+which= where
