Where he wrote the hymn of labor by Jose Rizal?

Jose Rizal did not write a hymn specifically called "Hymn of Labor." He wrote many poems, including:

* "A La Juventud Filipina" (To the Filipino Youth), which is a patriotic poem calling for young Filipinos to strive for excellence.

* "Mi Ultimo Adios" (My Last Farewell), a poignant and moving poem written shortly before his execution.
