How to connect the load of capacitive three-point oscillatorb

Capacitive three-point oscillator
    The capacitive three-point oscillator is an oscillator that uses an LC circuit in the feedback loop to produce the required phase shift and can be used as
a resonant filter that only passes the required oscillation frequency.
    ①Colpitt oscillator. As shown in the figure (a), when an external load is connected to the output of the oscillator , connect the load with a small resistance value through capacitor coupling, or connect the load through transformer coupling to eliminate the load.
The effect of resistors,
