I just found that the big fish tank in the office broke by itself, because there was no one around in the surveillance. Will it be bad? Is this a sign?

In fact, there is no need to make a fuss. This may be a natural phenomenon, such as glass glue cracking or thermal expansion and cold contraction. Explain from the perspective of feng shui: the fish tank represents wealth, and the rupture of the fish tank means that you have to break the money recently. The solution is to spend money on relatives or friends, buy something or invite people to dinner.
