The last drop of human water will be tears of regret after environmental destruction. Raise environmental awareness and protect our beautiful home. Build a beautiful border and protect our homeland. The earth can meet human needs, but it cannot satisfy human greed. The green mountains clear my eyes and the flowing water calms my ears.

Use resources rationally, protect ecological balance, and promote sustainable economic development. Protecting the environment is a matter for everyone. A happy life lies not only in abundant food and clothing, but also in clear water and blue sky. Pursue green fashion and move towards green civilization.
