TV series "The Nanny and the Security Guard" plot introduction, episode-by-episode plot introduction, and the grand finale.

The nanny Da Miao and security guard Guo Liang of the residential community in Gao Du's version caused a great stir. On the wedding day of middle-aged security guard Da Ding, they helped young nanny Er Mei elope. Since then, the new nanny Yao Qian in Yao Qian's version has been missing. Da Ding not only lost his wife but also his money, and he was furious. He forced Da Miao to hand over Er Mei, but after being refused, he swore that Da Miao and Guo Liang would not have a single peaceful day. Although he appears rough and tough on the surface, he is actually cunning and calculating, with each move more poisonous and cruel than the last. First, he falsely accused Da Miao of colluding with Er Mei to defraud him of his money and belongings. Then, he designed a scheme to steal a resident's valuable puppy and framed Da Miao, claiming that Da Miao and Guo Liang had stolen and sold it. The "evidence" he fabricated was so convincing that even the police believed it. As a result, Da Miao, who had always been praised as a model nanny in the community, fell into disgrace and faced difficulties. However, Da Miao adheres to the truth and bravely takes responsibility for protecting her fellow nannies, facing the situation head-on as she maneuvers against Da Ding. On the other hand, Guo Liang, who is loyal and kind-hearted, has changed. It's as if he owes Da Ding an unpayable debt, enduring everything passively and greeting him with a smile.
