Based on the following symbol definitions:
* L @ M means M is to the East of L,
* L # M means M is to the South-West of L,
* L \$MmeansMistotheSouthofL,\ast L$ *$MmeansMistotheSouth-EastofL,Basedontheexpression$ \text{P \# Q @ R \K}, find the direction of K with respect to P. (Assume all points are placed at equal distances according to the given directions.)

Let's decode the relational positions from the given expression \text{P \# Q @ R \ K}$onebyone:1.$ \text{P \# Q}$:QistotheSouth-WestofP.2.$ \text{Q @ R}$:RistotheEastofQ.SinceRisdirectlyeastofQandQissouthwestofP,RalignsontheverticalaxisdirectlybelowPifdistancesmatchproperly.3.$ \text{R \K}: K is to the South of R.

Let's represent this on a coordinate layout assuming standard distance steps:

* Let P be at origin $(0,0)$.
* Q is South-West of P $\to$ Q is at $(-1,-1)$.
* R is East of Q $\to$ R is at $(-1+1,-1)=(0,-1)$. Notice that R has $x=0$, meaning it is directly south of P.
* K is South of R $\to$ K is at $(0,-1-1)=(0,-2)$.

Looking at the coordinates of K $(0,-2)$ relative to P $(0,0)$, it lies directly on the negative y-axis.
Therefore, K is to the South of P.
