Maybe I didn't pay attention when I bought it, and then I didn't take the lantern ear or missed it. Most leaders don't care too much, so you don't have to worry too much, don't think too much, just calm down and work hard.
Hanging lanterns at home pays attention to symmetry, whether it's a wedding or a birthday. It's unlucky that one person can't hang up one. Of course, this symmetry can be not only two, but also six, eight and so on. You can't hang four, because four is unlucky.
Hang lanterns until after the fifteenth day of the first month. A unit hanging lanterns is not limited to two, but also symmetrical and even, in order to get a good luck.
