I am a Chinese and speak Chinese ,so I only know it .I also Study English and can speak English and understand it,But not expertly.I hope someone can teach me English and I teach him or her Chinese and its culture,do you ?
I speak both languages, English and Chinese fairly well. But I cannot claim to be expert on either of the language as both aren't my mother's tongue. Its good to learn foreign languages to ease our interaction with other nationalities.
