about me

Hello, I’m Yan Sir, the person behind Inquiry Freedom.com.

I have been doing online marketing for almost 6 years. I have good luck and achieved financial freedom. I am currently studying more ways to make money at home full-time.

In the process of studying, I found that there are few high-quality Chinese resources on the Internet.

I know that novices need to experience painful struggle to get started, so I created the Free Enquiry Network to share what I know with you.
