Today, I installed the Linux system (armbian) on a development board, but the Chinese cannot be displayed. The manufacturer said that the mirror is not perfect and needs to be solved by myself. So to check the solution online, you only need to install the following software:
sudo apt-get install fonts-arphic-uming
Restart the computer after installation.
