暖阳深处是我心
[nuăn yáng shēn chŭ shì wŏ xīn]
Translated as 'deep inside the warm sunlight lies my heart,' this shows that warmth, care, hope, happiness exist inside oneself and they have become an inseparable entity, implying that no matter the external environment changes how drastically, the internal world remains calm, peaceful yet optimistic.
