If you want to learn spoken English well, there is a basic step:
1. Listen more: Listen to authentic English materials, such as movies, radio and TV plays.
2. Imitation: After listening, imitate and start with simple sentences.
3. Practice: Find a partner to study with and speak boldly.
4. Application: Look for all available opportunities to show your English.
To achieve the above four steps, online courses are not impossible, but the effect is much worse. So I think it's better to report to the oral English training class. You can go to Changsha to show situational English, which is in the forefront in Changsha. Of course, there are other institutions, and we must find the way that suits us best.
