Xi Shi
In contemporary mandarin, the Shih Tzu is generally known as the "Xi Shi dog"; Xi Shi was regarded as one of the most beautiful women of ancient China. Shih Tzu were nicknamed the Chrysanthemum Dog in England in the 1930s. The dog may also be called the Tibetan Lion Dog, but whether the breed should be referred to as "Tibetan" or "Chinese" is a source of both historical and political contention, as the subsequent section notes. A book on the breed states that "dog historians tend to have very strong opinions" on the subject.
