Wait, I'm not sure who Zambo Salvito is. Maybe a historical figure? Let me check quickly. A quick search tells me that Zambo Salvito was a 17th-century Philippine hero, a mulato or zambo who was tortured to death for refusing to betray his people. His story is often cited as a symbol of resistance. Okay, so the article should be about his life, historical significance, and maybe the PDF guide that's available.
