Kun Ai has a referee profile on FootSam that collects registered matches and competitions. The match history shows which teams met in the matches where the referee has a documented assignment. The season sections make it possible to follow how the assignments are distributed over time. Card statistics and other referee figures are shown in relation to the matches included in the records.
You can open a match to see its results, events and possibly the referee team. The competition connections show in which leagues the referee appears in FootSam's data. The profile thus provides a path from a single referee effort to a larger match history.
