幸福就是生死相守幸福就是罘离罘弃
[xìng fú jiù shì shēng sĭ xiāng shŏu xìng fú jiù shì fú lí fú qì]
This nickname translates roughly to 'Happiness is guarding each other between life and death; happiness means both together forever', implying a belief in enduring loyalty, companionship or undying love through thick and thin. Despite challenges faced ('罘离罘弃' refers metaphorically to trials and tests), being together makes everything happy and fulfilling.
