It's a cargo flight, after all.
Many/most passenger airplanes handle cargo business ordinarily. (Amtrak who thinks it's an airline, took it to extremes; ordering hundreds of baggage cars specifically for freight, you had Amtrak trains with 25 baggage cars and 5 coaches. Their freight railroad hosts told them to knock it off.)
However, the COVID-19 crisis has caused great shifts in the economy - largely ending the passenger business, but a veritable "gold rush" in the air freight business, particularly for emergency supplies that cannot wait for the slow container ship.
Your particular flight is from China, which as you know is where a tremendous amount of material is manufactured. And it's to Europe, which is pretty much the worst case for container-ship shipping times (must either transit Panama, Suez, or best case, a double transload for a rail crossing of North America). As such, the flight you mention is surely kept plenty busy by that traffic.
They can use almost the entire baggage hold for freight, and some airlines are pulling out seats so they can load cargo in the passenger area. This is perfectly legitimate; in fact many airliners are made as "Combis" that either convert quickly, or have a cargo section aft of the passenger section.
