Don’t do small things for good, do n’t do small ones for evil. ”This is a thousand-year-old saying,. which is the correct understanding of it? ['Only small things are worth doing.', 'The development of things is a process from quantitative change to qualitative change. Great good and evil are all developed from small things.', 'Doing things dare to face challenges, doing evil must do great evil, easy things are not worth doing.', 'Should be "for the small good, for the big evil".']
