After Qiu Society died, Meng Chuansheng lied that Qiu Society had robbed and shot the police, and he arranged for Qiu Society to run away. After a long time, Meng Chuansheng gave Feng'er a sum of money again, saying that it was given to her by Qiu Society, because Qiu Society killed someone and he could not return to China, let alone let her see him, and he could not even make phone calls to prevent being tracked by the police.
