那一抹笑穿透了阳光
[nèi yī mŏ xiào chuān tòu le yáng guāng]
'That smile breaks through the sunshine,' means that the mentioned smile was bright and infectious enough to overshadow or exceed the brilliance of sunlight itself. It describes moments filled with pure joy, which feels even more potent compared to the beauty and warmth provided by natural light. It emphasizes how significant and memorable this smile was, evoking emotions that can pierce deeply and leave lasting impressions like rays of sun piercing through clouds.
