Here's a breakdown of the issues and some possible interpretations:
* "Bonjour" means "Hello". This part is fine.
* "Bien fait" is a common phrase that means "well done".
* "Ta connaissance" is a bit confusing. It could mean "your knowledge" or "your acquaintance" but it's not a typical way to use those words in a greeting.
Possible interpretations and corrections:
1. "Hello, nice to meet you." This is the most likely meaning the speaker intended. The French phrase for this would be "Bonjour, enchanté(e) de faire votre connaissance".
2. "Hello, good job getting to know you." This interpretation is less likely but could be used in a very specific context where someone has been working on getting to know another person.
It's important to consider the context in which the phrase was used to determine the speaker's true meaning.
