assigning an average value of all second hardness of raw water to the target hardness of raw water.

3 . The method of claim 1 , wherein the determining the target hardness of raw water of the water softening device based on the target geographical area where the water softening device is located and the correspondence further comprises:

determining, in accordance with the determination that no hardness of raw water matched with the target geographical area is included in the correspondence, a plurality of second geographical areas that are within a preset distance range from the target geographical area from the correspondence;

determining a third geographical area among the plurality of second geographical areas, and determining third hardness of raw water corresponding to the third geographical area from the correspondence based on the third geographical area; and

assigning the third hardness of raw water to the target hardness of raw water.

4 . The method of claim 3 , wherein determining the third geographical area from the plurality of second geographical areas comprises any one of the following:

determining, randomly, a third geographic area from a plurality of second geographic areas; and

assigning a second geographical area that meets a preset condition among the plurality of second geographical areas to the third geographical area,

wherein the preset condition comprises any one of the following:

a raw water supplier in the second geographical area is the same as a raw water supplier in the target geographical area; and

a raw water source in the second geographical area is the same as a raw water source in the target geographical area.

5 . The method of claim 1 , wherein obtaining the correspondence between the geographical area and the hardness of raw water comprises any one of the following:

receiving the correspondence between the geographical area and the hardness of raw water transmitted from a server; and

receiving the correspondence between the geographical area and the hardness of raw water transmitted from a terminal.

6 . The method of claim 1 , further comprising:

obtaining updated information of the correspondence between the geographical area and the hardness of raw water, and updating the correspondence between the geographical area and the hardness of raw water with the updated information.

7 . An apparatus for determining hardness of raw water of a water softening device, comprising:

an obtaining device for obtaining a correspondence between a geographical area and the hardness of raw water; and

a determining device for determining target hardness of raw water of the water softening device based on a target geographical area where the water softening device is located and the correspondence,

wherein the correspondence is obtained by detecting hardness of raw water of respective geographical areas, and associating each of the respective geographical areas with a detection result of the hardness of raw water corresponding to each of the respective geographical areas,

wherein the determining device is configured to:

determine, in accordance with a determination that no hardness of raw water matched with the target geographical area is included in the correspondence, a first geographical area closest to the target geographical area from the correspondence;
