In making these works of art, one must use the exact same materials for the exterior and interior that would be used in making an actual architectural structure. The piano inside Rose Mansion is made of the same materials as a real piano, and the oil painting was carefully painted by an artist who made constant reference to the original painting. Even the trivets on the tabletops are made of real porcelain and stoneware!
所謂真材實料，就是建築外觀與內部裝潢的材料，都要求必須與實物無異，玫瑰豪宅中的鋼琴就是按照真實材料製作、油畫是照原畫縮小比例的細緻油畫、桌上所放鍋盤也是貨真價實的磁器或陶器！
