Printing to Bluetooth Module

I’m curious if I use the println() command on a bluetooth module connected to (RX0/TX1) where does it print to? There must be something critical I’m missing. If I initialize the liquid crystal library with the numbers of interface pins like so LiquidCrystal lcd(12, 11, 5, 4, 3, 2); I can do something like lcd.println("hello");. So by using the following program I’m not sure how it suppose to work on 2 pins. This doesn’t print in the Serial Monitor when using the bt port and baud rate.

#include <SoftwareSerial.h>

//We use the pin 2,3 for TX & RX 
SoftwareSerial bt(1, 0);
void setup(){
  // set the data rate for the SoftwareSerial port
  bt.println("Hello, world?");
void loop(){
  bt.println("Are u there world?");
SoftwareSerial bt(1, 0);

You can't do software serial on the hardware serial pins.
