What species of shrimp is "delicate pale colored river shrimp"?
Wikipedia works well as a contextual dictionary in these cases, so I just C+P the chinese name in Wikipedia and it gave me this: 

https://en.wikipedia.org/wiki/Longjing_prawns 

In that case you should be looking for river prawns (a.k.a. freshwater shrimps, depending on where you live), and a quick search in google gives you this guy: https://www.siamcanadian.com/freshwater-shrimp.html
