The Aso Boy carriage was filled with small black dogs of various postures, not so much a train, but a moving playground, naughty little black dogs, occupying every corner of the Aso Boy. More valuable is the service of the flight attendant, patiently and meticulously accompanied the children to play, no matter which country they come from, no matter what language they speak. The daughter, along with the other children, is intoxicated by the unique atmosphere of the Azu Boy. Parents can buy a coffee at the shop and sit leisurely, take a souvenir card and knock on a chapter to mark the memorable trip. If you have children, feel it.
