what is the best way?

Find a good teacher first.

watching dramas with the subtitles on helps alot!

My opinion is try to find a chinese friend, and contact with her or him everyday in chinese.

It would be best if you started with the basics, such as learning the Chinese alphabet (pinyin), tones, and basic grammar structures. This is to build a solid foundation before moving on to more advanced concepts. Mandarin is a tonal language, meaning a word's tone can change its meaning.

Listening to native speakers and practicing pronunciation and intonation are essential to developing fluency. Thus, you can find a language partner and also surround yourself with Mandarin content, such as music, TV shows, movies, and podcasts. This will help you become familiar with the language, improve your comprehension and conversation skills, and learn about Chinese culture.
