Where is Jinxian's best fortune teller?

I know there are three good sages, one is from the Wuli Deng family (the blind man has a mother-in-law to knock on? ) there is also a thinner son who is also a fortune teller and knocks on the street every day? . The other is the mother-in-law Fortune tellers who are together are all together (average income). Those who have the ability are all alone.
