I want to send the parcel to the tourism class of the central campus of Ximenkou Electronic Science and Technology School in Luojiang County, Deyang City.

That depends on how you use it. For example, the express address of the postal service should be clearly written. If you use Shentong, Tong Yuan, Shunfei, etc., just write down the travel class in the central campus of Ximenkou Electronic Science and Technology School in Luojiang County, Deyang City, and add the phone number (the courier must go to this place)
