1. A method for processing video data, comprising:
determining, for a conversion between a first region of video and a bitstream of the first region, a first history motion vector predictor (HMVP) table associated with the first region based on at least one of multiple HMVP tables,
wherein the multiple HMVP tables include one or multiple HMVP tables associated with neighboring regions of the first region, and the multiple HMVP tables are used to store motion information associated with the neighboring regions coded prior to the first region, or
wherein the multiple HMVP tables are associated with other regions, the multiple HMVP tables are used to store motion information associated with the other regions coded prior the first region, and the first HMVP table is determined by generating a new HMVP table based on the multiple HMVP tables; and
performing the conversion by using the determined first HMVP table which includes at least one motion candidate.
