Sumubok din akong makipag-usap sa mga Pilipino sa lansangan ng lungsod. = I also tried conversing with Filipinos in the streets of the city.

I would instead say that as “mga Pilipinong nasasalubong ko” (Filipinos I meet (in the streets). Also, we would more often say, “Sinubukan ko ring (rin na)/ding (din na) makipag-usap…” instead of “Sumubok din akong makipag-usap...”.)
