Longest handshake chain

According to Official Guinness Records,

The longest handshake chain involved 3,434 participants and was achieved by the Hong Kong Blind Sports Federation (Hong Kong), in Hong Kong, China on 2 November 2013.
The participants included visually impaired participants, students from primary and secondary schools, members of local organisations/corporations such as Rotary Clubs and Standard Chartered Bank. Over 400 volunteers stood by to fill in the gaps to complete each section of the stadium, 200 of which were used and counted towards the final total. Due to the threat of a category 3 typhoon hitting Hong Kong the day of the event, the record attempt was brought forward by two hours.
