心若止水不为谁起波澜
[xīn ruò zhĭ shuĭ bù wéi shéi qĭ bō lán]
The phrase suggests having a heart still like water, untouched and not ruffled by any external influence. It expresses inner peace, emotional steadiness, or even indifference toward others, symbolizing self-restraint, composure, or an unwillingness to become emotionally engaged with or swayed by anyone.
