the presence of mutations 16189 and 16217 make you belong to this well established Asian familly type called B4. Great daughter of a lady carrying the N haplogroup 70 to 60 000 years ago and whose descendants gave birth to R 10000 years later, we have to wait another 10000 years to see the first baby B girl in Asia (East India or Indochina). B4 then arrived in southeast Asia more than 45 000 years ago. The first Asian ladies with B4c must have been living in south east china or Indochina more than 35000 years ago and lived ever since with the descendants of one of her sister who were B4a and whose descendants colonized the Pacific (the Austronesian speakers). Your ancestors did not follow these Austronesian people, they must have belonged to a large group since we see members of this  B4c group spreading around south east Asia (SEA) and to island southeast Asia (ISEA) (Indonesia). Only a very few members of the same group moved to Siberia. Another little group along with other groups of the B family moved to Japan 30000 years ago. The rest of Your ancestors probably decided to remain in South east Asia till the present day. 10000 years ago, one possibility is that, like many did before them, some of this B4c group decided to follow the land bridge between China and Taiwan. When they did this they remained isolated till the last 400 hundred years before present. But, actually Your closest ancestors belong to the group that did not cross the straight and acquired the 16092 mutation between 10 and 5000 years ago. The ones that moved to Taiwan lost 16311 and can be found among the Tsou and the Yami, but also in Puyuma and Paiwan and Batan and Luzon in the Philippines. Today in Taiwan both groups are seen in Taiwan as many of Your ancestors migrated there, and one can distinguish these different B4c that moved to Taiwan only recently (Your ancestors) by the presence of the recent 16092 mutation.
The other possibility requires more study. It would show that B4c came to Taiwan from the Philippines and Indonesia.
Both alternatives show a long Southeast Asian Origin and a very recent arrival in Taiwan.
