The Three Hundred Tang Poems is an anthology of poems from the Chinese Tang dynasty (618–907). It was first compiled around 1763 by Sun Zhu (1722–1778), who was a Qing Dynasty scholar and was also known as Hengtang Tuishi (蘅塘退士, "Retired Master of Hengtang"). Various later editions also exist. All editions contain slightly more than 300 total poems. The number 300 (or more exactly 305) was a classic number for a poetry collection due to the influence of the Classic of Poetry which was generally known as The Three Hundred Poems.
