1. A wearing prompt method for a wearable device, comprising:
obtaining, by a wearable device, a target photo plethysmo graph (PPG) signal;
identifying a reference wearing position of a plurality of reference wearing positions corresponding to a position where a reference wearing parameter is greater than a predetermined reference value, wherein each reference wearing position corresponds to a different wearing tightness on the wearable device;
storing the reference wearing parameter;
storing a correspondence between the plurality of reference wearing positions and a plurality of PPG signals, wherein the plurality of PPG signals comprises a PPG reference signal; and
prompting, by the wearable device when the target PPG signal is inconsistent with the stored reference wearing parameter, a user to adjust a wearing position of the wearable device, and to adjust tightness of wearing the wearable device.
