In the cold winter season, a group of Shenzhen tourists and families drove into Changbai Mountain in the northeast. It was originally a fun trip, but due to the fault of his father A De, 8-year-old boy was unfortunately lost. The A De’s couple sought assistance from the local authorities, and the search and rescue operation was launched immediately. The golden rescue time has passed, after 24 hours, and the normal safety limit of 48 hours has passed, but the child hasn’t been found. Will the miracle of life happen?
