Shiu Shing Hong is a wholesale beauty products business in Sheung Wan, Hong Kong, selling fragrance products such as hotel scents and rose water. It carries Peninsula and Four Seasons scents and massage oils, and the fragrances can be diluted with 70–75% sanitizing ethanol for use in a diffuser. A line forms as early as 9:15 a.m., and customers choose by testing about 10 hotel scents at the center of the shop, where the owner also recommends massage oils. The shop gets crowded and the samples are old, making it hard to determine the exact scents.
