Sorry for late reply because recently was so busy on my project. Thank you every one for helping me. How does the positive feedback being fed back to the input in the oscillator?

C5 is part of the oscillator tank circuit, it will have voltage across it. This is used as an input to drive T2 gate. T2 is a source follower and drives a voltage across C6 to put power into the tank circuit.
