Episode 4 recap: Wei Jian Hao won the competition for Song Huai Xi.

When Song Yuan Er saw her sister, she didn't choose any stone, thinking that Wei Jian Hao had backed out at the last moment. She couldn't help but cancel a few words she had prepared for him. Liu Hao Shi helped Song Yuan Er choose a piece of window-opening stone, confidently assuring her that this stone would appreciate steadily. As the staff opened the window-opening stone, everyone anxiously awaited the result, but Wei Jian Hao had already left the stone-monitoring room.

Song Huai Xi originally thought she would definitely lose this time, but unexpectedly, the window-opening stone turned out to be a piece of waste material. In the end, Song Huai Xi didn't gain or lose anything, yet she won the competition. Song Huai Xi was very happy and wanted to celebrate with Wei Jian Hao, but she couldn't find him anywhere.

Wei Jian Hao arrived at the front yard of the Song family's residence, where he unexpectedly found a raw stone. When he touched it with his hand, he realized it was a piece of imperial purple. He praised the stone to himself, but was discovered by Mr. Song, who hoped that Wei Jian Hao would work for the Song family. However, Wei Jian Hao took this opportunity to propose a business partnership between the Song family and his girlfriend, Xi Li. Mr. Song agreed.

Xu, the organizer of the mining conference, originally wanted to use this competition as an opportunity to make Liu Hao Shi the core appraiser of the Song family, allowing a group of inferior goods to enter the Song family in order to bring it down. Seeing that this plan wouldn't work, he came up with another plan. There was a businessman named Feng Jian Ye who happened to have a large piece of material. Xu planned to use this large piece of material to understand Wei Jian Hao and assess the skills of the Song family's appraisers.
