Probably not (One can never be 100% certain). It's been a discussion that's been ongoing in CAAC (Think FAA) for the last ~10-15 years. Originally they planned to do that around 2015-2016 but the whole trump trade war shenanigans fucked up the supply chain for aircraft (Chinese carriers are usually using Airbus/Boeing and not ILs or their domestic builds). It took them sometime to popularize the domestic brand. My guess they would do it in 2022, but it seems they are quite confident on the current president in the USA, or desperate because they think the GOP will take the house/senate in 2022, not sure which.
The original plan was drafted back in around 2002-4 tbh but Hu Jintao (the former party secretary) wasn't strong enough to force a change through. Xi on the other hand certainly has the backing to force it through, question is will he survive the backlash from the military and the party secretaries? You have to remember in China there are four competing factions in general: The party (Which is splintered into factions and thus represented by the Politburo standing committee, the civilian non party (generally minor player, aka blue checkmark thots), the military (represented by the central military committee , the MSS (They are represented by the ministry of supervision/ justice systems).
Xi's reforms to the CMC in 2015 shook up the military pretty heavily, I am not sure if they are filled with lackey loyalists like the great purge era under stalin, but there seems to be at least some degree of talent in military modernization as evidenced in the type 625 SPAGG prototype (it's a unmanned version of the ZBL-08 IFV).
I don't know much about point air defence/ SPAAGS, so take the below with a grain of salt, the person who wrote this article seems to work at China National Electronics Import & Export Corporation due to his knowledge of the FCS and the electronic aspects of the weapon.
I've translated the portion of the article in question below. Bear in mind some of these terms are quite technical so they might not make sense:
The 625 protoype has a 6x25mm set of autocannons, is light, and has newly developed FCS [Skipping the propaganda talk...] The 25mm auto cannon carriage is 25x 287mm (Is that even an actual autocannon sized projectile???), The chamber pressure is higher than 430 Mpa, muzzle velocity up to 1150m/s, shell weight 670g 2ith 25g of HE, with a conical shaped fragmentation diameter of 5-6m. At the same time, due to the 25mm being smaller than the 35mm, the rate of fire is around 2000rpm versus the old 35mm SPAG (PGZ 88 and PGZ 63 iirc) of 888 rpm. [... More propaganda skipped] The 625 prototype utilizes a rotary barrel autocannon (Like a gattling gun), this new technology is also aided with 4 guided/infrared missiles (it's inaccurate here, I suspect its misses and not guidance systems as it could read due to the picture). It is planned for these new units to enter integration into the field at the brigade level as a point defense item. The estimated radius of intercept for small and light objects is expected to be between 3000-6000m. At the same time search, firecontrol radar and TV guided (literally: Electrical-probe system??) are mounted on the top of the vehicle, and thus can track and intercept a target at a max range of 10,000m in ideal conditions (which in tibet, is never), and can actively weapon track (By this I think it means track the flight path and thus engage at any time) 6-10 targets at once. It is expected there will be a centralized brigade HQ FCS and radar collator which should allow for the vehicle to engage targets without its radar.
tl;dr. PLA made a protoype of a SPAGG based off the tunguska concept with the M163 VADS gattling gun, and a possibly downsized crotale missle.
(The 2K22 missles are optical/radar guided whereas the crotale is optical/ir/radar guided)
Judging from the pictures, that's not in Lhasa because it's much more hilly terrain but lower elevation (and much more vegetation), I'd place it in བྲག་ཡིབ་གྲོང་ or Bayi, a town in ཉིང་ཁྲི་གྲོང་ཁྱེར། or Nyingchi prefecture. It's the only place to receive consistent rainfall that's also technologically stable enough to see trees grow that large, there's also not the characteristic rainbow stripe like soil coloration found in the far eastern end of Tibet
In regards to the gif. Was the Tibetan Military region receiving new equipment of HQ-17s (Chinese version of Tor with IFF and better radar), it shows 4 Launcher units with radar, a reloading vehicle, a command vehicle (centralizing the unit radar coverage), and a possible ammo vehicle (it's at the far left end).
