Hello, if you want to learn Mandarin financial programming or Mandarin programming, you can go to official website, the western foreign exchange market. They have launched a set of video teaching materials for financial programming training in Putonghua, and provided the video programming content of 10 in the previous chapter for free viewing. Obviously, you just need to download high-definition pictures. I used their Putonghua financial programming teaching in the early stage, which is not bad. If you have any questions in your study, you can contact them to explain. Recommend it and hope to adopt it!
