Address: Room and building of Chengdu University of Technology+Davidia involucrata Garden (Ginkgo Garden, Furong Garden or Banyan Garden), No.3 Dongsan Road, Erxian Bridge, chenghua district, Chengdu.

It's near Shilidian. Shilidian is an area, and the deliveryman won't know where Shilidian is.

If you don't know the specific address, you can just write "Chengdu University of Technology, No.3 East Road, Erxian Bridge, chenghua district, Chengdu 1". But it depends on how you use it. If so, ordinary mail at the post office won't do. If it's EMS express, just add the phone number. If other express delivery (such as Tong Yuan or ZJS) has a number, it will be fine.
