early 1900 ships Philippines to Hong Kong

Hello, I will appreciate any help someone can provide on ships that were transporting Filipino laborers from the Philippines to Hong Kong about 1908-1910. I know that the SS Mongolia was transporting the workers from Hong Kong to Hawaii for jobs in the sugar plantations. But I have hit a vacuum on how they got to Hong Kong. Once I know the names of relevant ships, then I can search for passenger/crew lists. Thank you in advance for any assistance.[:I]
