Former partners turned enemies: Jia Yueting and Ding Lei's feud

Jia Yueting and Ding Lei were once partners in LeEco Auto, but now they have become enemies due to copyright infringement. The two co-founded LeEco Auto in 2015, but Ding Lei resigned from his position due to health reasons after only two years of cooperation. Since then, Ding Lei has founded Human Horizons and HiPhi, while Jia Yueting continues to lead Faraday Future. Recently, the two sides have launched a legal lawsuit over intellectual property issues.
