坎儿井/Qanat for iranian
为伊朗文化引入了来自CK3的先进科技坎儿井，可以在高原，山地，丘陵，沙漠地形建造（限制在波斯和两河地区），完全抵消丘陵带来的邻近度等负面影响（山地仍然+25%）,在波斯种田愉快！

Advanced Qanats technology from CK3 introduced to Iranian culture, can build in plateau, mountain, hill, and desert terrains (restricted to Persia and Mesopotamia area). This technology fully cancels the negative effects like proximity caused by hills (while mountains still impose a +25% penalty).Enjoying farming in persia 😀
