1. First, you need to download the font from Huajun Software Park and install it.

2. After the installation is complete, you can enter some office software to install and use it.

If the Founder subscript Song font is not displayed in the application, you can try the following methods:

1. Install "Fangzheng imitation Song Simplified Chinese" in the machine you want to use.
2. Set "Embed truetype font" in the save tab of the machine's Word options that can be displayed
3. Use the font replacement function in the Word options of the machine to be displayed, and replace "Founder's Fake Song Simplified Chinese" with the "Fake Song" that exists in the system.

The above is all about how to use Founder Xiaobiao Song Simplified for free. I hope it will be helpful to you!
