What are the advertisements, slogans and poems about protecting blue whales?

I hope our descendants will never only see blue whales in books.

Don't let the blue sea lose the shadow of blue whales, so we should protect them.

The blue whale is one of mankind's friends. I hope our next generation can have such a friend, and today we should protect this friend.

Magpies are messengers of the sky,

Spread happy news,

Horses are loved by the earth,

Rush out the happy notes,

The blue whale is the spirit of the sea,

Send a message of peace.

The blue sea is inseparable from the ornament of blue whales.
