A huge maze as big as 26 soccer fields and running through corn fields has opened Wednesday in northeast China's Heilongjiang Province, the country's major grain production base.

Tourists are welcomed to get lost in a 21.6-hectare "tiger face" maze cut through corn, marking the Year of the Tiger this year, said Professor Liu Deming, the maze designer from Harbin Institute of Technology.

The maze, located in Lanxi County around one-hour drive from the provincial capital Harbin, would take more than one hour to complete if the longest path (10,000 meters) was taken, Liu said.

"It would only take half an hour if the shortest path was found," he said.

Liu said local farmers had planted the corn and later experts cut a tiger's face out of the plants with the help of an e-map, GPS and laser measuring equipment.

"Emergency exits and guides have been arranged in case any one gets really lost," he added.

Tourists could also enjoy the scene standing on a 50-meter-high hill nearby.
