O365: How to block emails by the senders description?

Let's say I have a company emailing me with addresses like
Lamp Shining Manufacturing Co.,Ltd sales07@xxxxxxxxxxxxxxxxxxxxxxxx<mailto:sales07@xxxxxxxxxxxxxxxxxxxxxxxx>
The address on the right is constantly changing. But I want to block based on the description instead.
I tried adding a rule

Apply this rule after the message arrives
with Lamp Shining Manufacturing in the sender's address
move it to the Junk Email folder
and stop processing more rules

I tested it by the run rule now function. It didn't work. I had to add the @ address to get it to work. Which, since it constantly changes, is pretty worthless.
