The shape of the 'setsu' (a pattern which was presented by Chinese emperors or kings to emissaries) drawn on the observer's right of the picture of the person buried in the tomb in the Mural Painting of Koguryo Tomb (such as in the Angaku No.3 Tomb believed to be from around the middle of the fourth century) looks like the Kasamatsu Pattern drawn on the Sankakubuchi Shinjukyo (Triangular-rimmed mirrors) (the one on the mirror is slightly more flat than the one on the mural painting), and assuming that the Kodo (Yellow Flag) tentatively given to Nashime by the Wei dynasty has the same shape as this setsu, it is possible that the shape looks like a yellow tachibana.
高句麗古墳壁画（4世紀中頃とされる安岳3号古墳等）の墓主の画像に向かって右側に描かれている「節（せつ）」の形が、三角縁神獣鏡に描かれる笠松文様に似ていることや（壁画に比べて鏡の方が少し形が平ら）、もし魏から難升米に仮授せしめた黄幢（こうどう）が、この節と同じ形をしているものと仮定すると、黄色い橘の形にも見える可能性はある。
