Qingdao celebrates 70 years of the Chinese navy

"It is a rare opportunity to get onboard and see domestic and foreign naval ships at one time," said Guo. "My father served in Chinese army, and I have a deep affection for naval vessels."

Anowar, a serviceman from a Bangladeshi ship, said he was happy to see so many Chinese visitors.

"I really wanted to visit downtown Qingdao, but we only have one day to tour the city, and will leave on Friday," he said, adding that he looks forward to his next chance.
