Japanese mahjong and cards, others 4 times 12000, mine 4 times 5200, why?

In Japanese mahjong, the number and number of cards drawn are determined by the type and number of cards you listen to. If you have the same number of cards, but different points, this may be due to the following reasons:

1. Different cards: the same number may have different cards, such as peace, upright, cup mouth, etc. Different cards have different points.

2. Different card numbers: Even for the same card type, if the number of cards is different, the points will be different. For example, all three colors are the same. If you add three, the score will be lower than that of adding four.

3. Other players' Hu cards: If you touch your own Hu cards, the points will be lower than other players.

When comparing your own snapshot with others, you need to confirm whether the above factors are the same. If they are the same, it may be the difference in points caused by different scoring rules or agreements between players.
