Video tutorials
Launch week produced plenty of Jev videos, with uneven quality. We selected 21 (5 Chinese + 16 English) and verified every title and channel via the YouTube oembed API (2026-09-22).
Titles and channels verified via the oembed API (as of 2026-09-22). Exact publish dates cannot be verified through public APIs, so the original page is authoritative — we do not guess. Summaries are written by this site’s editors and do not represent the authors’ views.
