七厘米海岸八千米蔚蓝八厘米海岸七千米蔚蓝
[qī lí mĭ hăi àn bā qiān mĭ yù lán bā lí mĭ hăi àn qī qiān mĭ yù lán]
The phrase translates to alternating descriptions ('7 cm of coast, 8 km blue sky, then 8 cm coast, 7 km blue'), suggesting an endless, almost poetic landscape repeating in an almost artistic fashion. It represents a continuous cycle of beauty or scenery, perhaps highlighting the constancy or repetition found in nature’s vastness.
