1. A data encoding method comprising:
obtaining an attribute residual of a current point cloud point;
binarizing the attribute residual to obtain a binary code of the current point cloud point, the binary code of the current point cloud point including a first binary code indicating a first flag bit and a second binary code indicating a second flag bit;
selecting a first context model from a context model list;
selecting a second context model from the context model list, the first context model and the second context model being different models;
encoding the first binary code using the first context model; and
encoding the second binary code using the second context model.
