Thank You Very Much Kungfu English

Dear Suzy, Thank you for your explanation. I understood. Sorry for replying so late, because I'm very busy in recent days, mostly on work issues. However I still managed to keep learning in my spare time. I can understand almost 80 percent of each lesson in stage 4, in condition of not listen the "lexical units". So I feel very happy and proud. I want to express my sincere gratitude toward the Kungfuenglish. Thank you very much! Best regards Rock
