After entering Nan Commandery, Lü Meng treated the civilian population well, among whom included family members of Guan Yu's troops. He also gave strict orders to his men, forbidding them from disturbing the people. In one incident, Lü Meng executed one of his soldiers for stealing from a civilian household, even though that soldier was an old acquaintance of his. He shed tears after that. This incident shocked the other soldiers in Lü Meng's unit and they did not dare to defy his orders. Lü Meng won the hearts of the people by showing kindness towards them – he provided necessities such as food and clothing to the elderly and the poor, and distributed medicine to the sick. He also ordered the treasury in the commandery office to be sealed up while they awaited Sun Quan's arrival.
