Shao and Huang have cooperated for many years and invested a lot of human and financial resources in the research and development of a new product. Shao Guohui learned that China is promoting the “Belt and Road” and decided to return to China for development. Huang Shuaihuan was not clear about Shao Guohui's intention to return to China, thinking that he was absconding with confidential information, so he tried his best to sneak into Shao's house.

In the process of implementing the plan, it caused an outrageous ending.
