From my research, here is just some information about Masuki.
Mami was brought in by Ma Mon Luk (马文禄), an elementary teacher from Guangzhou, China, who emigrated to the Philippines in 1918. Arriving penniless, he peddled chicken noodle soup around the city. It became a hit as the locals loved the hot noodles made from eggs, and in the 1930s, he established a noodle parlor in Binondo that bears his name. The restaurant was changed to Makong, then later, Masuki. The word “mami” was derived from Ma (马), his surname, and Mian (麵) or Mi in Fookienese, meaning noodles.
