Tips

usage
Use zài for physical loading and carrying: 装载 (to load), 载客 (to carry passengers), 载重 (load capacity), 超载 (overload), 车载 (vehicle-mounted), 搭载 (to carry / be equipped with). For written records and the literary 'year' sense, switch to zǎi.
memory
Both readings hang on the cart radical . Picture a single cart with two jobs: physically hauling cargo (zài) versus carrying the inscribed history of a journey (zǎi). When the cart literally bears weight, say zài; when it bears a written record, say zǎi.
