Students from the School of Life Science, Liaocheng University, volunteer to raise public awareness on environmental protection, calling for spending a cleaner, quieter and safer Spring Festival by lighting less fireworks, on Jan 14 at a local park in Liaocheng, Shandong province. Their campaign slogan reads: "Be cautious when lighting firecrackers; let's act first for safety and environmental protection."
