In 2016, we designed some supply stations, The underground city, and initial concept sketches of the engine for the Chinese science fiction film 《The Wandering Earth》. In the initial concept design stage, these things didn't even have any details, because at that time we only cared about its shape and more visual scheme positioning.

2016年为中国科幻电影《流浪地球》设计了一些补给站、地下城和发动机的初始概念草图。在最开始的概念设计阶段，这些东西甚至可以没有任何细节，因为当时我们只关心它的形状和更多的视觉方案的初始定位。
