Can simplified and traditional Chinese be mixed in a calligraphy work? thank you

As long as it is used properly, because many words have been written in two ways as early as the Tang Dynasty, but words must have the same meaning before they can be mixed, such as holding and holding. For those complicated words with different meanings, be careful not to make mistakes when mixing them. For example, it is right for the queen to use the simplified word "Hou", but it is wrong to use the traditional word "Hou". Another example: writing an ugly year cannot be written as an ugly year.
