The above pages and clips are all composed of "Leisure and Cultural Affairs", and the theme of the short film is "Keep the swimming pool clean". In the past, the public swimming pool occasionally found feces or vomit, so it was necessary to temporarily close the swimming pool for circulating filtration and other procedures, which affected the swimmer's ability to swim freely. These situations often involve young children. Therefore, LCSD takes the cartoon character "McDull" as the propaganda protagonist, aiming at children under 1 1 and their parents who accompany them to swim in the swimming pool, publicizing and educating the information of keeping the swimming pool clean, especially not to urinate or vomit in the swimming pool. Lyrics: grandma teaches "belly" to move, and swimming is not good! Grandma teaches boys to wash and swim, which is not easy. Hey! My grandmother taught me that it is not easy to swim and feed if you want to "spit milk"! It's dirty. Don't let others swim. Narrator: The children keep the swimming pool clean. Lyrics: Grandma taught you to swim and stay "pork brisket". Screen cover: keep the swimming pool clean. Photo reference: LCSD/ swimming manual/cleaning/graphics/photos/posters _ popup.
