The second child of the Meng family, a tall, slender young man with refined features inherited from his father Meng Rong. He carries himself with the grace of a scholar from ancient times. Unlike his sisters and parents, his attitude toward Meng Anran is the most natural and composed, showing no unease or distance, though Meng Anran perceives it as resignation rather than genuine warmth. He is described as normally doting on Lu Qingcheng the most, making it surprising that he quickly agrees to clear out Lu Qingcheng's belongings from the shared bedroom to make room for Meng Anran. He is responsible, helping care for his younger brother Meng Chenghong.
