应yìng接jiē不bù暇xiá

Literal: responding and receiving, no respite
Figurative: To be unable to keep up with everything coming at once, be it customers, requests, news or sights; it began as praise for a landscape.

Where does 应接不暇 come from?

It comes from the Shishuo Xinyu, in the chapter "Yanyu." The calligrapher Wang Xianzhi, son of Wang Xizhi, said that when you walked the roads of Shanyin, today's Shaoxing, the hills and rivers set each other off so that you could not take it all in. In other words, it began as praise for scenery: there was so much to look at that the eye could not keep up. Today it is used for anything that comes at you all at once, be it customers, requests or sights; when it is only the eye that is overwhelmed, 目不暇接 is also very common.
