For instance, nowadays when one sees a Chinese-style roof with upswept eaves, the red beam high up in the middle is actually made from a tube of compressed paper. The light, cheap paper tube is wrapped in a layer of gauze and covered in red paint. Unless you actually tapped it, you wouldn't know it was paper.
像是在餐廳裡看到一個中國式人字形的捲棚屋頂，那高掛中間的紅樑其實是高壓紙筒做的，輕便、便宜的紙筒先包上一層紗布，再上紅漆，除非敲上一敲，看不出來是紙做的。
