(I) Guanzhong situation in 1951 This year, the situation of midge, midge, and Midian were somewhat different from last year. In terms of area, more areas were discovered this year than last year. That may have expanded this year than last year. However, we believe that those areas were originally affected by insects. Last year, the number of insects was relatively small and they were undetected. This year, with appropriate environmental factors, they multiplied and were discovered. New discoveries this year include Fuping, Dali, the north bank of Lintong Weihe River, Qianxian County, Liquan County, Changwu County, Yixian County, Yongshou County, Chunhua County, Yiyi County)
