Black screen appears when installing centos 8 but centos 9 stream can be well installed

I have tryed to install centos 7, centos 8, centos 9.But only centos 9 can be installed.
I have already checked the checksum.Checksum is right.
Now I need to use Centos 8.Is there any way to help me solve this problem?
cpu: Hygon C86.

Does it work if you use the basic graphics option that's under the initial Troubleshooting menu when you first boot?
CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are dead, do not use them.
Use the FAQ Luke

I've tried, but it doesn't work.Selecting this also causes a blank screen.
I may have found the reason.Linux kernel supports the hygon cpu in 4.20,but linux kernel in Centos 8 is 4.18.

RH backport support for hardware, bug correction and some features, so vanilla kernel is vanilla kernel and red hat kernel is red hat kernel

if you want to use Centos 8 for production, then use another RH clone, Centos 8 is dead and Centos 8 stream IS NOT RHEL8 clone.

have you tried text install mode? do you need graphics?
