The Kunena team has announce the arrival of Kunena 6.2.6 [K 6.2.6] which is now available for download as a native Joomla extension for J! 4.4.x/5.0.x. This version addresses most of the issues that were discovered in K 6.1 / K 6.2 and issues discovered during the last development stages of K 6.2
Your post is in wrong place.. Chinese language hadn't been updated for a while when we released Kunena 1.7, so we had to drop the support for it. Now it's updated again, so you might want to find the language files either from KED or from translations category in this forum.
