五音不全也要哼着我的歌
[wŭ yīn bù quán yĕ yào hēng zhe wŏ de gē]
Even without being skilled at singing (literally 'five notes complete', implying musical talent), this individual insists on humming his/her song. It suggests perseverance and positivity when doing something, regardless of the obstacles encountered, showing self-love and an optimistic attitude.
