Lee Hsing directed the "grief 'portion, while Li Han-hsiang directed" joy ".) The technique involved the construction of a miniature water mill set inside a very small filming studio. The trick worked superbly, and many other directors later borrowed the technique. Lee Hsing used it in Execution in Autumn to enhance the sense of depth and the general atmosphere.
李行特別指出，李翰祥在拍《喜怒哀樂》中的「樂」時（白景瑞、胡金銓、李行分別導喜、怒、哀），由於經費有限，在很小的攝影棚裡，採用「強迫透視」搭建的水車磨坊佈景，效果出奇的好，後來許多導演都學他，他拍《秋決》就用此方法，加強了景深和氣氛。
