弘治帝
Emperor Wen is also famous for having the fewest concubines for an adult Chinese emperor. (Emperor Fei of Western Wei and the Ming dynasty Hongzhi Emperor were the only two perpetually monogamous Chinese emperors.) Emperor Wen was known for having only two concubines (although he might have had additional concubines not documented by traditional historians), with whom he might not have had sexual relations until after the death in 602 of his wife Empress Dugu, whom he loved and respected deeply.
