The Guishui River in Yanqing, Beijing, is a 5A-level scenic area with extremely stringent environmental protection requirements. Lijian's new campsite product, Arki Star—a wilderness accommodation and entertainment modular system—comprises residential, bathroom, and soft-connecting corridor modules. Each module features standardized connection ports on all sides, enabling seamless assembly into enclosed indoor environments. In regions with extremely challenging construction conditions (such as islands or mountainous forests where terrain is rugged, sites are confined, heavy machinery is impractical, and power supply is limited), This rapid hotel room construction system, requiring only two or three workers for low-cost assembly, proved its worth during the Guishui River project.

北京延慶媯水河是5A級風景區，對環境保護要求十分苛刻。立建新的營地建筑產品Arki Star——是一種野外住娛模塊系統，由居住、衛浴和軟質連廊等多種模塊組成，這些模塊都擁有各方向的標準連接口，通過連接口模塊間可相互連接成封閉的室內空間環境，在建設條件十分苛刻的地區（在海島、山林等地區道路崎嶇不平、施工場地狹小、大型機械無法使用甚至電力條件不充分），僅靠兩三個人力就可以輕松低成本完成的酒店客房快速建設體系，在媯水河項目中快速搭建使用，經受住了考驗。
