Chinese languages

Apparently 㨗 is a variant of 捷. 捷思 appears to be the Mandarin transliteration of the name Jessie (Jie Si), so maybe that's not a good candidate.

I'm beginning to learn Cantonese and am working on my Chinese name. I plan to use my wife's maiden name (蔡) as my surname. My mother-in-law has proposed using 㨗思 as my given name. I'd be interested to hear interpretations and thoughts on that name (when used in Cantonese and Mandarin).
