In 1941 one of the Chinese troops, led by Pan Tiande, was defeated by the Japanese, and arrived in the Soviet Union by contacting the Soviet army. Officer Natasha was then responsible for their training. During the following military actions Pang's patriotism and bravery deeply moved Natasha, and they fell in love together. After the founding of New China Pang decided to serve the country as a mechanic worker, and Natasha became a soviet mechanic specialist after college. When they were preparing for the wedding, Natasha was ordered to return to the USSR. The departure was very dramatic. Later, Natasha wrote to Pang that she had settled down on the border, trying to be as close as possible, waiting for him to come one day.
