All arrows pierce the heart, so the array:
At the top of the Lisboa Casino, there is a circle of sword weapons. Knife-shaped "weapons" form a circle and stab in all directions, which is a thousand arrows kill array. This is the most complete and special explanation about the layout of Feng Shui in Portugal, which is also the famous "birds return to their nests". It turns out that such a casino can be surrounded by 360 degrees, making gamblers a caged bird at the mercy of others.
