The most important festival for the Daban Yao is the Abo festival. It falls on March 4th of the lunar calendar (around Easter) and necessitates reunion and thanksgiving. People seek to bond and even restore broken relationships. They use song and wine to mediate and strengthen ties.
All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation. 2 Corinthians 5:18
