This scenic spot was inadvertently visited. The children wanted to go in. When they saw the ticket, they only got 10 HK dollars, 5 HK dollars, and immediately bought the ticket. They thought they would read some pictures. They didn't realize that there were many interactive games, such as weightlessness on the moon walk, space missions, and all of them were free, unlike in some parts of the country, they had to collect extra money. Parents with children should not miss this scenic spot.
