One man surnamed Lei, from the eastern province of Anhui, was rewarded for his two-day wait in line with tickets to the final of the 110 m hurdles.
"I just feel so lucky to be able to see Liu Xiang run at the Olympics," said Lei, 24, referring to the Chinese hero and defending champion.
Wang Zongmao, 73, also queued for two days to secure tickets to a diving event.
"It's been tough, it's very hot, but it's worth it to participate in the Olympics," Wang said.
Long queues had already formed by Wednesday afternoon, a day after Olympic organisers announced the final tranche of 820,000 tickets would go on sale.
