Instead of just pointing out the ... unprincipled ... approach of the chess organization here, there are some good things here that I have not seen elsewhere.
Anyone can become the champion. This means that anyone can play, and by being good can become the national champion the first time they attend.
The common approach in many countries in the west divides players into classes, and you have to advance through the class system until you reach the master classes. First then, the ones in the highest master class get to play for the title. For most players, a national championship is just about promoting to the next class. Here in Taiwan a good player can really come from nowhere to national champion.
Also, I like that already in the semifinals many games are played. Eleven rounds of Swiss to pick the top 12, allows a good player to blunder one or even two games away (it is semi-rapid time control), and still have a chance to be in the top selection. Imo the pressure to win every game and the luck of the pairings are less that way than with, playing something like five rounds.
In the final group the top 12 plays a round robin group, so that sould be quite fair. My only worry is the (understandably) tight schedule.
