Student Skype from teacher to me voice quality good, but from me to teacher voice quality bad so not practical for lesson if she can't hear me well. Also my requirement is more professional business mandarin. Would like to know if any italki mandarin teacher specialize in that. Technical voice quality must be good both direction though.

Teacher 是啊，最近网络通话不理想，耽误时间。会好的*__*希望你能找到有经验的专业商务汉语老师。如果需要帮助，欢迎联系*__*
