Is it necessary to learn mandarin Chinese for a disciple who attends Christian Chapel in China?

I think alittle required if you usually go to the Chapel much times,
come again, learn more different language is so helpful for you anyway.

Hi,i believe that learning Chinese need you exercise frequently,and you should

communicate with others in Chinese often,I also learn English, I believe that

learning Chinese just like you are learning a language ,you just need to

exercise ,exercise and exercise.
So if you are a beginner,i trust you need to find a professional mandarin

teacher to help you learn Chinese and get more skills of learning Chinese .
You can find some good Chinese movies and musics and search some Chinese forum

to make more friends to let you make a lot of progress.
I hope my answer could help you a lot.
