According to the Englishman Barlow's A Journey in China, the British emissaries once presented a portrait to Emperor Qianlong. An important minister in the court pointed out the shadow of the nose as portrayed in the painting and said, "A flaw in the jade! it's really a shame!"
根據清朝時英國人巴落所著的《中國遊記》，英國的使臣曾經送了一幅西洋的肖像畫給乾隆，一位大臣就指著畫像中鼻子的陰影說：「白璧之玷，良可惜哉！」
