"古詩十九首" by Tong Xiao is a collection of nineteen ancient Chinese poems likely composed during the Eastern Han dynasty between 140 and 190 CE. Written by anonymous educated elite authors, these influential verses explore timeless themes of separation, longing, and life's transience through the voices of traveling men and waiting wives. Featuring plain language yet refined expression, these five-character poems shaped centuries of Chinese poetry with their melancholic tone and universal emotions that continue resonating across cultures and eras.
