In short, there is no shortcut to speaking standard Mandarin, only listening and reading more! ! !
If you want to learn Mandarin well, the first thing is to insist on speaking every day, which is very important, and at the same time pay attention to finding your own problems when speaking. After discovering your own dialect problems, you need to find the correct training method, and you can consult your teacher to carry out targeted training. At the same time, we should also pay attention to the pronunciation of some people who speak standard Mandarin every day, including students who listen to the radio and speak Mandarin well around them. In addition, if you have time, do some reading training every day and practice step by step in the order of ancient poetry-poetry-prose. In short, Putonghua learning is also a language learning, and only by perseverance can it be effective. Generally speaking, as long as it lasts for 3-5 months, it will have certain effects, and some people have made great progress. I wish you can practice Mandarin well!
