• Shizuka Shirakawa：Pictogram (象形) of tools used for weaving ropes.^[1]
• Ji Xusheng: Ideogrammic compound (會意 / 会意): 魚 (“fish”) + 二 (“two”) – to catch two fish at once (kill two birds with one stone).^[2] Compare the oracle bone script form of 亟.
• Xu Shen: Ideogrammic compound (會意 / 会意): 一 (“one”) + abbreviated 冓 – to catch two fish at once.^[3]
• Ideogrammic compound (會意 / 会意): 一 + 冓 (“the shape of a basket repeatedly woven from bamboo”). It signifies the concept of repeating something that was once done, conveying the meaning of "again."^[4]
