Who knows the exact birth time of Xiang Yu?

Xiang Yu (232 BC-202 BC) was born in Xia Xiang (now Suqian, Jiangsu). The grandson of Xiang Yan, a famous Chu-Han general, was a famous strategist and hero in ancient China. After Chu's death, he went into exile with his uncle Xiang Liang in Wuzhong (now Suzhou, Jiangsu). When I was young, I couldn't learn calligraphy, but I still couldn't learn sword. Determined to learn "the enemy of ten thousand people" (that is, the ability to resist ten thousand people), I learned the art of war from my uncle. But I just have a "little knowledge" and refuse to study. Xiang Yu is eight feet tall and can carry a tripod. When he was young, he was ambitious. When Qin Shihuang visited Zhejiang (now Qiantang River), Xiang Yu saw his horses and chariots commanding, and blurted out, "You can replace them." In the first year of Qin Ershi (2009), Chen Sheng and Guangwu rose up in osawa Township. Xiang Yu responded with Xiang Liang in Wuzhong. Twenty-four-year-old Xiang Yu was pushed onto the historical stage by the storm of the people's uprising.
