In any case, the upper-level department is responsible for business leadership, so in such a situation, it's up to the upper-level department to decide.
Tang Fangjing naturally did not know about these matters, and even if he did, it would not matter to him; for him, this case must be completed at all costs.
He is well aware of the intricacies involved, but he chooses not to concern himself with them at the moment.
After several more days, the Tangfang City Bureau finally received instructions from the upper-level department, indicating that the case should not be filed yet and that a preliminary investigation should be conducted at Dajin first.
Generally speaking, formal investigations require filing the case first, and only after filing can the Public Security Authorities employ many investigative measures.
However, this does not mean that investigations cannot be conducted before filing; such actions are called preliminary investigations.
