Satellite photos of Pangong tso show no permanent LAC transgressions but buildups on both sides
Notice how that image shows the ITBP base at finger three still under Indian control, disproving Pakistani OSINT claims.

Basic sumary:
Ajai Shukla's claim doesn't hold up based on available evidence
Chinese buildup mostly with in the claim line, or lac, except for one location about 500m in the Indian side.
At that location, there are at most a few dozen tents and no permanent structures yet, disproving Shukla's claims about thousands of Chinese troops in Indian controlled territory and bunker construction
India matching Chinese deployments only a few hundred meters away.
Be careful. they may issue a warning.
