What is the correct way to read the circuit diagram (amplifiers)?

Question

Electronics

Judging by the npn structure of the transistor, it can be deduced from the rule that "the base current drives a large collector current." So on the emitter we have a slightly amplified signal. But why then is there a direct connection between the collector of the previous and the base of the next transistor? Why does a large current not immediately go to the base of the second transistor, but goes to the collector? And why do we need feedback?

Answer 2

why do you need feedback?

Where is the feedback in this diagram?
