你好，我有興趣知道更多電梯既資料：）

我也是一位工程師（電信），多多指教

我不懂得打中文，希望不好介意

By your professional advise , is there difficult to pass those test which EMSD require your administration on the lift ?

Also , in your point of view , what kind of service level we (normal citizen) should expected as well ?

Thanks for your idea and my pleasure that for your reply
