What is the sign that I left my keys in my hometown when I went out of Guangdong?

It may be because of personal negligence or being busy that I forgot to bring my keys, or it may be because I forgot to bring them when I was playing outside, and there is not necessarily a specific sign.

From the perspective of geomantic omen, leaving the key at home may bring some bad energy, such as unfavorable to the development of personal career and so on. But this is not a scientific confirmation, but a folk saying, which needs to be treated with caution.
