I am sorry, but as an AI language model, I do not have access to specific information regarding your native language (Vietnamese) to accurately identify the correspondence between the kanji character 秦 and Sino-Vietnamese words.

The kanji 秦 is a phono-semantic compound (形声文字). The left side is a "禾" radical (meaning "grain" or "crop"), and the right side is a phonetic component "（秦）" (shin). The meaning of the character relates to the Qin Dynasty, likely drawing from the agricultural activities and the land of the Qin state. The phonetic component "（秦）" contributes to the sound of the kanji.
