The theme of "Challenging Days" series is mountains. All of us are climbing up our own mountain, aiming to reach our goals and dreams. No matter we achieve our goals and dreams or not, we must be proud of our footsteps when we look back at all the difficult trails we have gone through.

【堅毅人生】系列的主題是山脈，雖然每個人要行的人生道路不盡相同，但都同樣是在攀爬自己的山，向著自己的目標和夢想進發。最後，不論我們的目標和夢想達到與否，回首一看時，我們能為所行過的路，或美麗，或艱辛，而引以為傲的，這就不枉此生了。
