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 current block being predicted in an intra directional mode;
when the intra directional mode of the current block is associated with an angle that is one of smaller than 90 degrees and larger than 180 degrees, determining whether a delta angle associated with the current block is a pre-defined delta angle;
when the delta angle associated with the current block is not the pre-defined delta angle, applying a single direction intra prediction to the current block; and
reconstructing a sample of the current block based on an adjacent reference sample on a reference line that is determined according to the applied single direction intra prediction.
