Hello I saw a comment that mamali is looking for money like others and... I know mamali very well He did a great job for us. He taught for years without receiving money and was a very important element in the development of people who did not have a good teacher (which led to several of his students winning gold in the Iranian Olympiad). He taught us that we can help others regardless of material things. And we continue his work I said this in response to someone who said that this person is looking for money like everyone else nd... I said this because if he was looking for money, he could have earned a lot from teaching at this high level. In the end, thank you very much, I hope you will be successful in your work And sorry if my English is not good enough :)
