The lucky officer, Zhou Sicheng, 26, from Jing'an District Public Security Bureau, won a six-day tour package for two to Indonesian capital Jakarta and the Batam Island, as well as 3 million Indonesian rupiah (US$331.50) in spending money.
Zhou is entitled to free return air tickets and 5-star hotel accommodation.
The policeman said he didn't have a girlfriend to go with him and plans to use the prize after the Expo because police aren't allowed time off during the event.
"I will try to find a girlfriend by then. If I can't, I will take my mother," he said.
Zhou said the bureau organized the pavilion visit for policemen yesterday.
He decided to visit the Indonesia Pavilion because the queue wasn't long and its design was attractive
