difference between to go in the house and to go into the house

to go in the house  - байшин луу орох......
to go into the house - байшин руу орохоор явах.......

difference between "go in" and "go into"

You would say "I just walked in the door" for "I just entered (the room or building I am presently(яг одоо, одоо) in)."

"I just walked into the door" contains a phrasal verb using "into" to indicate direction but not entry. The speaker walked up to and hit the door with his body (usually, as the result of an accident).

other expressions....
To be into something: "I'm really into that TV show." = I'm very interested in that TV show." The "into" here is a transferred usage from the "into" in "to get into" where "into" indicates direction.

To run into someone. "I ran into Joe today." = "I unexpectedly met Joe today." or, in a different

context, "I collided with Joe today."

• If you are already inside a location and you're not indicating movement from exterior(гадаад) to interior(дотоод), you can use "in":
