我姓温我心稳
[wŏ xìng wēn wŏ xīn wĕn]
The literal translation is 'I'm surnamed Wen which means temperature, my heart stays stable/ steady', which suggests they come from a family where composure is valued and expected. Wen (温) refers to temperature, so it indirectly implies being neither hot-headed nor cold-blooded, but consistently mild.
