Sun Liang
Lady Quan was the daughter of Quan Shang (全尚). Her mother is the daughter of Sun Gong, the grandson of Sun Jing. Her relative Quan Cong married Sun Luban, a daughter of Wu's founding emperor Sun Quan. When she was young, she looked pretty and was favoured by Sun Luban. Every time Sun Luban entered the palace, she took Lady Quan to visit her father. When a succession struggle between Sun Quan's sons Sun He and Sun Ba was ongoing, Sun Luban, who had a feud with Sun He's mother, urged her father to arrange a marriage between Lady Quan and Sun Liang (another of Sun Quan's sons born to Lady Pan) because Sun Liang and his mother were becoming increasingly favoured by Sun Quan. Around 250, the succession struggle between Sun He and Sun Ba concluded when Sun Quan deposed Sun He from his position as crown prince and forced Sun Ba to commit suicide. Sun Liang was designated as the new heir apparent to the Wu throne.
