In 1962, significant changes occurred in the districts of Que Duong and Vo Giang, which were part of the broader economic and infrastructural development in Vietnam. The search results indicate that a major irrigation and drainage scheme was constructed in 1962 to cover areas including Que Vo and Yen Phong districts. This scheme aimed to irrigate 32,821 hectares and drain 51,711 hectares, which would have had a substantial impact on local agriculture and the economy.

While the specific changes in Que Duong and Vo Giang districts are not detailed in the search results, it is clear that the broader region underwent significant development efforts during this period. The construction of the irrigation and drainage scheme would have likely led to changes in land use, agricultural practices, and possibly the socio-economic conditions of the areas involved.

For more detailed information on the specific changes in Que Duong and Vo Giang districts in 1962, further historical records or local archives would need to be consulted. The provided search results give a general idea of the development activities in the region but do not offer specific details on the two districts in question.
