没看懂.

by implementing which the level of daily operation and management of the Department of Engineering没看懂.
你好, 这句话的关键在于, 关系代词" which" 所引导的非限定性定语从句用来说明前面整个句子的情况或者主语的某一部分.
在远句中,"which" 代指之前提到的几项措施：A; B; C; D; E; and F
代入, 意思上是by implementing A;B;C;D;E;F, the level of daily operation and management of the Department of Engineering in the Datang Four Seasons Garden has been improved.
但是英语语言表达上是by implementing which...
意思为:
[通过实施A; B; C; D; E; F几大建议, 大唐四季花园工程部的日常运作管理水平得到了提升.]
希望这样解释能够对你有所帮助.

通过实施工程部门的日常运作和管理水平


机器翻译的，算是帮得上吧！

这个是半句话吧
通过实施（前面提到的某个东西），工程部的日常经营管理水平（句子不全）

通过实施该级别的日常运行和管理工程部，
这不是一个完整的句子，只是句子的一个状语部分。
