The 15th painting is just based on the simplified strokes. It must be the 15th painting. However, if you choose a name based on three talents and five grids, it is not a 15th painting. It’s really hard to say. There are 16 strokes in Traditional Chinese and 19 strokes in Kangxi (because it is written as “璿” in the Kangxi Dictionary). Indeed, many calculations are based on the strokes in the Kangxi Dictionary. This also causes the problem you are talking about. Some say 16 paintings, some say 19 paintings, and the calculation results are naturally different. I suggest you give up this word if you are really worried about calculating good or bad luck or scores.
