"Working under the blue sky and white clouds" in Engpsh can be expressed as "working outdoors" or "working in the open air." This phrase comes from the imagery of being outside on a clear day with a blue sky and white clouds, as opposed to being inside or working in an enclosed space.

Examples:

"I love working outdoors, it's so refreshing and invigorating." (我喜欢在户外工作，这很清新和活跃。)
"I can't stand being cooped up in an office all day, I need to be out in the open air." (我受不了一整天都呆在办公室里，我需要出去到户外。)
"I prefer to work on my laptop under the blue sky and white clouds" (我喜欢在蓝天白云间用笔记本工作)
