Rizal traveled extensively through Hong Kong, Macau, Japan, the United States, and various countries in Europe from 1888 to 1891. Some key experiences included meeting O-Sei-San in Japan who became his lover and tutor, observing racial inequality in the US, and developing relationships with other Filipino expatriates. However, he also faced challenges like family troubles back home and disagreements with other Filipino leaders over the direction of propaganda efforts. Throughout his travels, Rizal continued advocating for reforms in the Philippines through his writings.
