Dear Henry
Knowing that you have trouble writing Chinese characters. I'm writing to offer my advice to you.
To write the Chinese characters well, you should write them neatly and sonorously without any faults, and you should write them on the lines or in the squares. Since each Chinese character is consisting of many parts, you can take apart the character and practise writing the parts. Then if you can write the parts well, you can combine them. What's more, you can also buy some calligraphy literature, which can help you develop a better sense to write the Chinese characters. Most importantly, you can keep a diary in Chinese characters. This will have a good effort to your handwriting.
Looking forward to your early reply!
Best wishes
