Shenmue III

When you first arrive at the Sunflower Grove in Bailu, 4 children will ask to play hide and seek with you. You have to locate them all to advance the story. The first is in the sunflower field. The second is on the roof of a house next to a ladder. The third is behind the Western most house next to the large wheelbarrows. The final kid is hiding inside a house further away from the rest. Go behind the 4 main houses and follow the road down toward the river to a lonely house. The door is cracked open. He's hiding inside.
