The frog is our good friend. If you want to erect a placard for him, what will you write on the placard?

You and I join hands to protect frogs and let them sing happily in the fields.

1. Harming frogs is harming humans themselves. 2. Protecting animals is your and my duty. 3. Live in harmony with animals and jointly build a harmonious society. 4. Maintain ecological balance and protect animals. 5. Don’t let human beings become the loneliest life. 6. Protect frogs, protect wild animals and maintain ecological balance. 7. Frogs are loyal guardians of farmland.
