India-China Faceoff: What happened in the 'Finger-4' area?

Indian soldiers have set up barbed wire obstacles at points where Chinese troops have come a few metres away from their positions at the Line of Actual Control (LAC) in eastern Ladakh.
India has warned against attempts to enter its territory as Chinese People's Liberation Army (PLA) troops, armed with medieval-type weapons, have been making multiple attempts to take over Indian-held positions.
