Complete works of Du Fu's cardamom poems

The total angle is a teenager between the ages of eight or nine and thirteen or fourteen (ancient children divided their hair into left and right halves and tied it in a knot at the top of their heads, which is shaped like two horns, so it is called "total angle"). Tao Yuanming's "Murong Shige" is "from a general point of view, defended by a hundred Kubinashi". Cardamom is thirteen or fourteen years old to fifteen or sixteen years old (Cardamom is a plant that blooms in early summer, but not yet in midsummer, which means that people are still underage, so it is called "cardamom youth"). In Du Fu's "Farewell" poem, "Flowers are more than thirteen, and cardamom is in early February". Hair was tied when a man was fifteen (when he was fifteen, a man would dissolve the original corner and tie it into a bundle). There is a saying in "Wearing Li Ji" that "I want to go to college with my hair tied". When a woman was fifteen years old, when she reached the age of fifteen in ancient times, she put her hair up and clamped it with a hairpin, indicating that she had reached adulthood. There is a saying in the Book of Rites that "(a woman) died for five years in ten years". The weak crown is a man of twenty years old (the ancient man was crowned at the age of twenty, indicating that he had reached adulthood, so he was called "weak crown" because he had not yet reached the prime of life). There is a saying in the Peony Pavilion that "suddenly there is a life, but the year is pale and handsome".
