this is the house ( )luxun has been lived in.

这句话本身的语法是错误的。(不能用been）
应该是：
This is the house (that) LuXun has lived in.
或
This is the house (where) LuXun has lived.

填which
去掉In就填Where
where=in which

which 或that
去掉in 填where 定语从句。

1.this is the house ( where)luxun has been lived in.

2.this is the house ( which/that)luxun has once lived.
