About the bubbling browser small font library

Where can I download the small font library of Bubbling Browser? After downloading, which folder should I put it in before it can be used? When modifying the font, the system prompted me to download it from Tencent, but I couldn't find it, and the ones I found couldn't be used. I really couldn't see the traditional Chinese characters... Mine is a copycat phone and supports mrp. Could any expert please give me some advice...Thank you!
