You are the first person that I spoke English to Chinese with the most because I didn't dare to speak. I'm afraid that I'm going to say the wrong. But I thank you very much at all that made me not afraid anymore.
You are the first person I speak English and Chinese, with most. I hardly dare to speak. I am afraid that I will speak against. But I thank you so much that I'm not afraid of people.
