Why "HaangSaanTung"?
In Hong Kong, the suffix 「通」 (tung) carries real product instinct — the Octopus card, the tunnel pass — each one a single device that settles a single job. 行山通 needs no explanation: hear it once and you know what it does. Grandparents and children alike can say it.
Why Luwu?
Luwu (陸吾) is the guardian beast of the Kunlun mountains in the Classic of Mountains and Seas — a human face on a tiger's body, the keeper of the peaks. Luwu AI Lab building a device that keeps hikers safe follows naturally. The auspicious tiger in the logo is Luwu itself: it guards Kunlun, and HaangSaanTung guards you.
Daai Lou Zai
The device is 行山通. The AI voice inside it is 「帶路仔」 (daai lou zai) — roughly, "the little guide." "HaangSaanTung's little guide says: it's downhill ahead, take it slow." The English name is TrailTung.
