What happen when the Japanese invaded nanjing?

When the Japanese invaded Nanjing in December 1937, they captured the city after fierce fighting, leading to the infamous Nanjing Massacre. Over a period of six weeks, Japanese troops committed widespread atrocities, including mass executions, sexual violence, and looting, resulting in the deaths of an estimated 200,000 to 300,000 Chinese civilians and disarmed soldiers. The invasion and subsequent massacre highlighted the brutal nature of the Second Sino-Japanese War and left a lasting scar on Sino-Japanese relations. The event remains a significant historical and cultural memory for China and is a subject of ongoing discussion and controversy.
