Bilingual Text Size Adjustments

I'm in need of a graphic designer who's skilled with typography adjustments, particularly with bilingual documents. The task involves enhancing the Chinese text to a larger size while keeping the English text in a smaller size, both of which are in the same material. Nevertheless, the proportion should remain aesthetically pleasing and shouldn't compromise readability. Here are the specifics:
- Larger Chinese text
- English text to be kept at the current large size
Proficiency in handling Chinese language layouts and a good understanding of visual balance in typography would be ideal for this project. The goal is to achieve a visually harmonious text presentation while ensuring clarity of both scripts.
