When you’re in Cambodia, or other countries with Buddhist as the official religion, shops such as Cheang Chea Sea are everywhere. Cheang Chea Sea is probably the shop owner’s name and they sell Buddhist religious stuff such as images of Buddha and other deities, ritual paraphernalia and other Buddhism-related items.
Details included in the sign are the name of the shop, best-selling products, as well as the shop address and contact numbers. However, only the name of the shop and the shop location and contact numbers are in English. The rest are in Khmer script.
