One web search result explicitly matches the claim that an elderly woman tried to fight a younger one over priority seating on an MTR train. Other results discuss different MTR seat disputes (e.g., involving an elderly man), meaning only one specific source corroborates this exact scenario.

The specific detail about the clip going viral on 'Saturday' is mentioned in the same source as Claim 0. Other 'viral' MTR results refer to different incidents (e.g., a woman with a Chanel bag or a man bullying a woman).

The provided evidence for this claim consists of generic 'Threads Downloader' tools and unrelated adult content; no source confirms the existence of a specific video on Threads depicting this event.

The evidence provided for this claim is entirely irrelevant, consisting of adult content and generic videos of elderly women, with no mention of the specific physical assault described.

This specific detail (younger woman not hitting back or verbally engaging) is found in one web search result. Other results describe 'heated exchanges' or different participants.

The detail about a fellow passenger asking the elderly woman to let go is mentioned in the same single source as Claim 4. Other provided evidence is irrelevant (movies, forums).

The evidence provided consists of the Wikipedia definition of a photograph, an Ed Sheeran music video, and a history of photography. There is no evidence of a specific photograph accompanying the post as described.
