東華大學的每間教室門口上方都會有門牌，光電系的辦公室在【理工二館E407】哦~有問題都可以來詢問，進來系辦前請記得配合防疫進行手部消毒，走到系辦助理的位置的時候，請告知我們一下您是誰，需要幫忙什麼？不然我們也只能看著您發呆。
At National Dong Hwa University, each classroom has a doorplate above the entrance. The Optoelectronics Department Office is located in Room E407, Science and Technology Building 2. If you have any questions, feel free to come and ask. Before entering the department office, please remember to sanitize your hands as part of the health protocols. When you reach the office assistant’s desk, kindly let us know who you are and what you need, or we might just stare at you in confusion!
