假设你是李华，你的英国笔友Tom最近给你来信，请根据下面信中所提的问题予以回信并提供相关建议。

Dear Li Hua，

How's everything? Do you remember last time you asked me to visit your hometown in the future? I was so thrilled at the idea that I signed up for a Chinese course at school.

However，it is not as easy as I thought. Chinese uses a writing system that is unfamiliar to English speakers. Chinese doesn't have an alphabet (字母)like we do. There are thousands of characters. That means have a lot of memorizing to do. And characters are just part of the learning. I suddenly feel at a loss. I was wondering if you could offer me some practical advice about this.

Looking forward to your reply.

Yours，

Tom
