Speaking with chinese is the best way, l think. And at the same time, waching Chinese drama or listening Chinese music will help you to learn it. You also need to know some background like culture. But case by case, hope you can find your way to learn Chinese very soon. Have a nice day!

There isn't a best way to become fluent in Mandarin. The only sure path to fluency is continuous practice and immersion. If you simply want conversational fluency, go live in China for a few years. If you want native-like control of Mandarin (knowledge of culture, idioms, language quirks, etc...), add few more years of serious language study to that equation. =)

Practice more, speak with native Chinese speaker.

I thik you should learn more words,because we have too much words. you have to know some frequent term and make your own sentens. after that practice more.
