As an important heritage of human civilization, classical gardens attach importance to the construction of artistic conception and perceptual experience. The study of classical gardens through spatial translation is helpful to trigger spatial speculation. In the digital age, the translation design of classical gardens is facing new challenges. The teaching contents and teaching organization need to be updated. Firstly, multi-dimensional spatial cognitive path can be built. The experience and perception can be strengthened by using network platform, aerial photographing and mapping, and XR technology. Secondly, it will break down barriers such as online-offline, centralized instructions-individual guidance, giving full play to the advantages of multiple information channels, and guiding independent learning and innovation. Finally, the modular teaching organization is used to improve the adaptability and controllability of teaching，which consists 6 teaching modules, 5 teaching methods, 4 theme lectures and 3 communication links.
