Almost from the age of two and a half years after the children began to play with him, from the suburbs, surrounding cities, to Hong Kong, South Korea, and then to the United States. Two and a half years ago, he rarely took him out because the childrens work and the adults were different. They had to sleep in the afternoon and afternoon. The food still needs to be prepared separately. It is inevitable that you will get tired and sleep badly during the trip. Because I don't want children to think that travel is a very difficult thing and create a shadow, I have never considered taking him to a place too far away. When the children are three years old, in addition to the nap time is a little longer than the adults, there is almost no difference between life and adults, there is no taboo on the food, the difficulty is reduced a lot, and travel abroad is on the agenda.
