Three advertising ideas are proposed: 1) A woman sprays celebrity perfume and is chased by men, requiring a main actress and 5 male actors. 2) Pets like cats and dogs play with families, including children, to elicit emotions from viewers. Multiple actors and animal props would be needed. 3) A young man engages in active hobbies like sports in jeans to showcase their durability, necessitating one main actor, background actors, and jean props.
