He Ning had no clue either. Other than the He family and the Xia family, there were only the Gao family and the Chu family. The Gao family was in the tobacco and alcohol business and made a lot of money from it, but their family was also very principled and had a good reputation in the capital. The Gao family was friendly to everyone. Even a beggar would be able to get a lot of money from the Gao family if he could get to know them.
As for the Chu family, they were in the steel business and very ambitious. The He family was in the business of essential goods. Although it seemed very substantial, it was actually not as valuable as the steel or tobacco and alcohol business. He Ning was only able to gain a foothold in the capital through his wiliness.
