Nobody, however, had claimed the prize by the time the final deadline passed to do so at midnight on Sunday, the newspaper said. The city’s branch of the China Welfare Lottery remained open up to the final minutes to allow the winner to come forward and claim the prize with their ticket. Lottery buyers are reminded by staff to keep their tickets safe as they are the only way to collect a cash prize.
