Only then can we strive for a better situation." "Concentrating all forces to fight to develop armed forces and establish base areas is your most important task. "The instructions require the Central Plains Bureau to" develop to at least 100,000 people and guns "within one year this year.""There are 100,000 troops in Central China, and there must be at least 1 million to 1.5 million Self-Defense Forces."
