202 1 stamp quadrangle Henan opera, which position is better, upper left or lower right?

Generally speaking, the position with the factory name in the upper left corner of most seal formats is the best, followed by the position with the factory number and color code in the lower right corner, but there are also a few seal formats that are not necessarily the same as the above seal formats.

For example, the positions of the four stamps except the third stamp in the 24 solar terms (two sets of stamps are big editions, and there are no four stamps at all) and the anti-Japanese war edition are fixed, so there is no room for choosing the position of the four stamps.
