As of February 12, 1968, there is limited information available regarding the Hanoi lottery system. During this period, North Vietnam was deeply engaged in the Vietnam War, particularly the Tet Offensive, which began on January 30, 1968. The Tet Offensive was a series of surprise attacks by the Viet Cong and North Vietnamese forces on cities and towns throughout South Vietnam. This military campaign significantly impacted daily life and governmental operations in both North and South Vietnam.
Given the wartime conditions, it’s plausible that regular activities, including any form of lottery operations, were disrupted or deprioritized. The primary focus of the government and the populace would have been on the war effort, affecting the availability of detailed records or analyses of such activities during this time.
For a comprehensive understanding of the Hanoi lottery system during the late 1960s, it would be beneficial to consult historical archives or contact Vietnamese governmental departments that oversee lottery operations. These sources may provide more detailed records or analyses pertinent to that era.
