Tie a knot in the garbage bag.

In an old community, residents throw their garbage bags in the dustbin, but when the wind blows, the garbage in the dustbin floats everywhere. When the wind blows, garbage is everywhere, and residents are miserable. Over the years, the workload of sanitation workers has also greatly increased. It's not that sanitation workers don't try their best, nor that residents don't throw garbage into boxes. The sanitation department has repeatedly warned surrounding residents to care for the environment. The slogan "Community is my home, caring for the environment depends on everyone" has been posted, but it still doesn't work. Garbage, especially some paper scraps plastic bags, is still flying, and the problem has not been completely solved. Even being monitored doesn't help. Even to the lawbreaker hell to pay, it is useless. For a time, it was very small.

On this day, the management of the community really can't come up with any feasible measures, and the superior will come to check. Environmental sanitation is the key point, and one-vote veto is implemented. So they asked the residents for suggestions on controlling flying garbage, and the good and operable suggestions were rewarded with 5000 yuan.

This is an unsolved problem for many years, and residents can't think of any good solutions. Only the advice of one pupil can solve the problem best. He said: just tie a knot on the garbage bag when throwing garbage, and then cover the trash can. Practice has proved that this proposal has a good effect. Tie a knot on the garbage bag so that it won't be blown away when the wind blows. Cover it, which is equivalent to another insurance. It is easy to solve a big problem that can't be solved for a long time.

Find the essence of the problem, a small action can help people solve big problems!
