Wait, the user asked to "Keep brand names". "Sin Miedo" is the title. Changing it to "Carente de Pavor" violates the brand name rule. I must keep "Sin Miedo". Also "Jet Li" and "Cheng Er".
Final check on "Sin Miedo". It is a proper noun (Movie Title). I will keep it. Final check on "Jet Li". Proper noun. Keep. Final check on "Cheng Er". Proper noun. Keep.
Let's refine the output.
Refined Synonyms: "para" (preposition): hacia (in context of purpose 'para' is unique, but strict instruction requires 3 synonyms). con. "en" (preposition): dentro de. Or just sobre. In the phrase "en español", synonyms are tough. "en" -> en. "y" (conjunction): e.
Okay, looks good.
