think the drain may be slightly blocked. Your best bet is to call a plumber now to fix it. If you leave it too long you may have toilet water coming up in other areas in your house. You can try to fix it yourself but most of the chemical treatments don't do a lot.
maybe bcuz to save water..
NO way
Sounds just like frozen piping
I will usually pick the toilet straight up and set it in the tub if there is one. Put a towel in first to protect the tub finish and then tip it front to back several times to cause the water to come out. You can set the toilet into a pan big enough to hold the bottom and then carry it outside or rock in in the pan. There is only about a gallon at most in the base of the toilet after you have flushed it.
The tub and toilet connect to the same drain at some point. The main drain was plugged but the connection between the toilet and tub was still open. Water seeks it's own level. When the water came up in the toilet, the tub was lower so some of it went there.
Putting toilet water into the tub with a cup.The real answer isWater seeks its own level and when a soil line (waste) is blocked water will find the lowest point to flow intoThus a toilet is above the tub and a basin is above the toilet.To prove allow water to flow in the basin and it should also flow into the tub
You have to use toilet more
This is not a venting problem. You have a possible blockage. Get a plumber to check your sewer lines. They may need to be cleaned out.
It's possible that you have a blockage, on the toilet line and the water is coming up in the tub to alleviate pressure. Or, your vent may be clogged causing what is called back syphonage, causing the water not to push out.

The clog is below the point where the toilet and the tub join the drain.
