1. I'm really not sure about this sentence. The 治病求人 somehow throws me off. My guess is it means something like "He asked the dragon king and got from him the white jade pot, which will help him to heal people (that asked for help)" 2. 如比 = so (formal for zhe4yang4), 之多= 多 as pointed out by other responder, 少不了=cannot do without..not 100% sure about the translation. My attempt would be, "There are so many springs, so there must be a name for it" 4. Jinan spring water's beauty is also reflected by this unique name
