"prompt": "An illustration depicting a historical scene of a closed and isolated country. The main element is a grand castle with high walls and a massive wooden gate, symbolizing the country's isolation. The castle is surrounded by a vast, empty landscape with no signs of foreign influence. The sky is overcast, adding a sense of isolation and solemnity. In the foreground, a lone guard stands watch, emphasizing the strict policy of no external contact. The style is realistic and detailed, with a focus on the architectural features of the castle and the solitary guard. Ensure no text is included in the image to avoid any potential errors.",
"explanation": "這幅插圖展現了一個歷史場景，描繪了一個閉關鎖國的國家。畫面中央是一座宏偉的城堡，高牆和巨大的木門象徵著國家的封閉和自守。城堡周圍是一片廣闊而空曠的景象，沒有任何外來影響的跡象。天空陰沉，增添了孤立和莊嚴的氛圍。前景中，一名孤單的守衛站立，強調了嚴格的不與外界接觸的政策。這樣的設計不僅能夠吸引學生和學華語的人士，也能有效地傳達“閉關鎖國”這一政策的封閉和自守。",
