The Jehovah's Witness denomination has been preached in more than 300 different languages, apparently using the English text as the base instead of directly from the original biblical languages. Surely, there must be some East Asian believers.
The reason why I raise this concern is that "filial piety" is the dominant cultural value of East Asia and overseas East Asians. In regards to Christianity, there was the Chinese Rites Controversy, which was resolved by Pope Pius XII, in which he declared that traditional Chinese Confucian practices were tolerated, as they did not conflict with Catholicism, and these practices were embedded within the culture. Among South Korean Catholics, they practice jesa, but the Roman Catholic Church has no problem with it either, seeing it as a part of the culture that does not conflict with (Catholic) Christianity.
Also, I searched "filial piety" on the Watchtower Online Library, and only two articles discussed it, and the two articles seemed to use filial piety only when it served the interest of the church.
Cultivating Faith in the Creator
As an old Chinese saying puts it, Among a hundred virtues, filial piety is the foremost. Surely it is proper that children know their father and honor their parents. (Ephesians 6:1-3; Colossians 3:20)
Can the Dead influence the Living?
CAN THE DEAD INFLUENCE THE LIVING? MANY people have a morbid fear of the dead. Some believe that spirits of the dead can either protect them as their guardians or harm them as vengeful ghosts. Many Chinese worship their ancestors as a way of showing filial piety (devotion to parents) and of ensuring blessings for future generations. Though such beliefs are common, the Bible clearly shows that the dead cannot in any way influence the living.

The author(s) of the two articles fail(s) to recognize that filial piety can actually manifest itself in both, which may hint that the denomination merely uses it to serve its own interests. In addition, as a sub-question, how does the Jehovah's Witness denomination deal with the filial piety among its East Asian believers (and those in the diaspora) in cases of disfellowship and shunning? Given that the JW denomination has a hierarchical church polity, has there been an official church pronouncement about this cultural value that may or may not conflict with this church denomination? So, does the Jehovah's Witness Watchtower have anything to say about the likely conflict between its own tradition and traditional Chinese beliefs and practices?
