Almost correct. The last war-sized conflict China took part in was the 1979 Chinese-Vietnamese war [1]. That was 45 years ago. Battle-sized events between China and Vietnam have occurred up to 1991 [2], that would be up to 23 years ago. Skirmish-sized events with India are as recent as 2021. [3]. As for what occurs in Gaza, I agree. Bad stuff has been happening there. Going by the tonnage of things blowing up, Gaza is a gang shootout compared to Ukraine, though.

Do you mind noting when/where bombs were dropped by the Chinese during the Chinese-Vietnam war, or any of the engagements you've listed? I'm having trouble finding any information about that.

I don't know the details. Wikipedia estimates Chinese losses as 26 000 killed, 37 000 wounded with 420 tanks and 66 guns lost. Vietnamese losses are estimated at 30 000 killed, 32 000 wounded, 185 tanks, 200 guns and 6 missile launchers lost - so it's safe to assume they didn't use butter knives.

Their preferred method of bombing might have been artillery, though - due to the lack of high capacity bomber aircraft, and due to lack of air superiority. Despite this, Wikipedia also mentions:

"The 372nd Air Division in central Vietnam as well as the 917th, 935th and 937th Air Regiments in southern Vietnam were quickly deployed to the north.[61]"

The Vietnamese source article is here. A relevant part seems to be this:

"When the border war began, the Ministry of National Defense also decided to send part of the 372nd Air Division (Hai Van Group) to the North to perform missions. From February 18 to March 3, 1979, squadrons of the 917th Air Regiment (Dong Thap Group), 935 (Dong Nai Group) and 937 (Hau Giang Group) including 10 UH-1 helicopters, 3 U-17 reconnaissance aircraft, 10 A-37 attack aircraft, and 10 F-5 fighter-bombers were deployed at Hoa Lac, Kep, Bach Mai and Noi Bai bases, respectively."

I'm unable to find more details.
