In all the world, สิ่ง (Sing , Thingan , สิ่ง) is a common largely masculine, but infrequently girly forename. The first name สิ่ง is characteristic of Hong Kong, where it is quite a common primarily masculine, but scarcely girly name, Macao, where it is quite a common unisex name, and Qatar, where it is quite a rare boy's name. Measured by absolute frequency, it is the most numerous in India, Hong Kong, and Indonesia. Much more prevalently, สิ่ง is the last name as well as the forename.
สิ่ง is also a name for the fictitious and mythical characters: Sing Hi , the musical character in the musical San Toy; President of the Board of Ceremonies.
