Chinese IQ game

This one's a teaser, alright. We've all seen the river crossing puzzle, with the fox, the chicken and the grain, and you have to get them across the river. well, this is a variant, and is an IQ test applied as a prerequisite to working in China.

The game can be found here, but because it's in Chinese, the rules are shown here:

• Only 2 persons on the raft at a time
• The father can not stay with any of the daughters without their mother's presence
• The mother can not stay with any of the sons without their father's presence
• The thief (striped shirt) can not stay with any family member if the Policeman is not there
• Only the Father, the Mother and the Policeman know how to operate the raft
• To start click on the big blue circle on the right.
• To move the people click on them.
• To move the raft click on the pole on the opposite side of the river.
