tofu

did he p a lot or just a little bit, did he p when you were at home or he was alone.

if you don't want him to p at that corner again, you can just simply put some "white pepper", the chinese one, at that corner. and he won't p and at corner again

if you want to find out the reason, you need to spend more time.
eg. if he p a little bit when he was alone, he may feel uncomfortable when he was alone.  you should not play with him just before you leave.  and you can slowly train him,  maybe start from one hour.

my dog will do the same thing when he  is mad.

my dog p on the carpet a lot, so my uncle told us to use 胡椒粉, the one that you add on 粥.  since we put 胡椒粉 on the carpet, he won't p overthere again.  but remember to reapply a significant amount of  胡椒粉 everytime after you clear the carpet.
i believe he doesn't like the smell, he got close to there and smelled it few times, then he would go away

oh sorry, it doesn't work for yours.  did you put a lot?
