It is a polite and informal way of asking someone to meet you. It is often used in situations where you are asking someone to meet you at a specific location or time.
Here are some examples of how "mil jao" could be used:
* "Kal mil jao?" (Meet tomorrow?)
* "Kya tum mere saath mil jaoge?" (Will you meet with me?)
* "Mujhe station par mil jao." (Meet me at the station.)
It is important to note that "mil jao" is a somewhat casual phrase. You would not use it in formal situations or when speaking to someone you do not know well.
