Ma Guodong, the owner of the "Guodong Restaurant" by the national highway, charged his ten-year old friend Lei Hong for a pot of hot water, and brought up ten-year-old old accounts, leading to the breakdown of brotherhood. Lei Hong transferred to the "Mancang Restaurant". The shop owner He Mancang was honest and reliable, insisting on clear pricing. Afterwards, in order to compete for the exclusive post station of Dingfeng Logistics, Ma Guodong used inferior meat to attract customers at a low price, causing people to be poisoned, and the shop was sealed up. In the end, He Mancang won the contract with integrity and genuine materials, and Ma Guodong was sentenced for illegal activities. The story reveals that affection cannot withstand calculation, and justice is in people's hearts.
