get a passing glance at 走马观花

“走马观花”，汉语成语，意思是骑在奔跑的马上看花（look at the flowers while riding a horse）。原形容事情如意，心情愉快，现在多指粗略地观察一下，大概浏览一遍。可以翻译为“glance over things hurriedly，get a passing glance at或gain a shallow understanding through cursory observation”。

例句：

这本书我只是走马观花地看了一下，对于书中的思想内容理解较肤浅。

I have just skimmed over the book so far, so I just have a shallow understanding of the ideological contents in it.

日程安排得很紧，我们只能在风景区走马观花地看一遍。

Our itinerary is well packed, so we can only get a passing glance at the scenery.
