Smoke and rain moisten the Qingming Festival, another season of nostalgia. Intention is precious, but don't forget that green smoke is easy to dissipate, but hidden dangers may last for a long time. In fact, it's also good to use different methods. Flowers can replace fireworks, lights can continue to show concern, and online worship can also warm and convey emotions. Civilized worship brings a peaceful home for longing. Guarding the green mountains and clear waters, starting from every clear memory, a fragrant heart beats the green smoke. Civilized sacrifices ensure safety, let our thoughts breathe with the mountains and forests, let us civilized sacrifices together. (New Society)
