After the outbreak of the War of Resistance Against Japan, under the call of Tan Kah Kee, the leader of overseas Chinese in Southeast Asia, the overseas Chinese formed a "Southern Overseas Chinese Technician Team" to work as drivers and maintenance workers on the Myanmar-Burma Highway to join the anti-Japanese national salvation movement. The TV series "The Heroes of Nanqiao Mechanical Engineering" is based on this background, telling the touching love story of young returned overseas Chinese transporting supplies on the Myanmar-Burma highway to save the country, and life and death.
