After Shen Jinghong is publicly kicked out by her original company, she seizes a loophole in the project contract, teams up with a client representative, and relies on solid field research and testing to win the public selection qualification. She and her partner Tang Qiao build a small team from scratch, overcome heavy obstacles such as capital shortages and malicious suppression by opponents, and win the park renovation project. Afterwards, they enter the old street district renovation, help distressed small shops, insist on field surveying, value original data, and reject false high-priced solutions. Facing Han Qiming's competition and various behind-the-scenes obstructions, Shen Jinghong strictly observes the rules, protects the rights and interests of merchants, and successfully wins the old street renovation pilot. At the beginning of construction, she encounters another emergency of mismatched construction material batch models.
