Yadollah Safdarzadeh Haghighi was another son of Mahdi Khan who left his studies in law and became a part of this brilliant family job. He wasn't only passionate about the high values of weaving but also about design and the harmony of colors. He came up with many wonderful ideas and worked with famous painters to help his imagination become unique rug designs.
Feyzollah Haghighi was the creative and active son who continued their family's heritage till the end of his life and also bequeathed this gift to his children. He studied Persian arts and miniature in the fine art school in Isfahan with great masters like Rostam Shirazi and Isa Bahadori and learned about Persian rugs from his father. Feyzollah Haghighi was appointed to an important position in Iran's heritage foundation and began restoring monumental historical paintings for many years. He mixed the mysterious beauty in Persian architecture with the design of Persian rugs and created unique artworks with the assistance of Norouz Hafizi and Rostam Shirazi.
Nasrollah Haghighi is Mahdi Khan's only child who is now in charge of their workshops. He still keeps their family names up in this industry, producing the best kinds of Persian carpets and impressing his brothers' and father's creativity. In addition, Mahdi Khan's grandchildren continue to value their fathers' and grandfathers' legacies. This family is one of the most influential families not only in Isfahan but also in the whole country because of their extensive efforts to revive the fascinating art of Persian carpets.
