The winning ticket was sold May 30 in Nanjing, capital of southern Jiangsu province. Till July 29, no eligible winners presented themselves, the Nanjing Daily reported.
In China, a lottery win expires 60 days after the ticket is sold. The Jiangsu Provincial Sports Lottery Centre later declared the lottery invalid, and the unclaimed money will now be distributed to a sports welfare fund for the benefit of social causes.
The centre said this was the seventh abandoned lottery ticket case with sums above five million yuan in the province.
