1. A method of video decoding performed in a video decoder, the method comprising:
receiving coded information of a current block and neighboring blocks of the current block from a coded video bitstream, the neighboring blocks including first blocks and second blocks, each of the first blocks being adjacent to one of a top side, an above left corner, and an above right corner of the current block and each of the second blocks being adjacent to one of a left side and a below left corner of the current block;
when one or more of the first blocks of the neighboring blocks and the current block are not in a same coding tree unit (CTU), excluding intra modes associated with the one or more of the first blocks from a most probable mode (MPM) list for the current block;
when the one or more of the first blocks of the neighboring blocks and the current block are in the same CTU, adding a respective intra mode associated with each of the one or more of the first blocks into the MPM list for the current block based on a sequence of conditions, the sequence of conditions indicates an order in which a propagated intra mode associated with each of the one or more first blocks is added into the MPM list at a position immediately following a position of an intra mode associated with the respective one of the one or more first blocks;
adding a respective intra mode associated with each of the second blocks of the neighboring blocks into the MPM list based on the sequence of conditions; and
reconstructing the current block based on the MPM list.
