Ask a literary master to give you couplets, couplets related to the best thing like water

The best kindness is like water that swamps thousands of things.

There are eight main taboos in couplets. Your first couplet is already "ten thousand", and the second couplet must be bigger, otherwise it will end at the end. Unfortunately, ten thousand and billion are both oblique sounds, which is against the rules again. In this case The 7-character couplet must follow the principle of "135 does not matter, 2467 must be reversed", and the first couplet must end in a flat tone, and the second couplet must end in a flat tone. "Water" and "things" are already banned, and it's really difficult to remedy them. If possible, you could change the first couplet to "The best is like water, which moistens thousands of things," and the second couplet is "Thousands of virtues can nourish things for thousands of years."
