捂着心别喊痛
[wŭ zhe xīn bié hăn tòng]
Translates closely to 'Cover your heart and don't shout pain'. This implies resilience - a quiet, stoic endurance against personal suffering, suggesting someone who keeps emotional pain to themselves, presenting a strong front. This kind of nickname might suggest that its holder is emotionally guarded, private, but strong and independent in handling inner turmoil.
