Dear Automoon (my compatriot) – the Moon orbits itself around the Earth!
French and English will easily be mixed up not only by spellings but also the pronunciation. My English is getting poor because I have been learning French myself for almost two years. Before that, I would like read fictions in English all the time.
My advice to you is that English has become an International English – to master it is a must!
In my opinion, French is a cultured language, so if you have time and energy. It is no harm to learn it, and further to that, because of the advent of the internet, you can read lots of information in French as well as enhancing your vocabularies in English.
My Dear friend, I wish that you had a bright future no matter you are in China or abroad!
