若无人伴你愿成自己的太阳
[ruò wú rén bàn nĭ yuàn chéng zì jĭ de tài yáng]
If No One Is with You, Be Your Own Sun means that when no one else offers support or companionship, one should still try to remain positive, strong, independent, providing oneself warmth and brightness as needed, encouraging self-sufficiency in the face of solitude.
