Flowering on the bar is a mahjong term. Blossoming on the bar means that when there are three identical cards (both of which can be uncovered), another identical card is taken by oneself or grabbed from others to form a bar card, and then the next card is a card that wants to be Hu. Note that mending flowers does not count as blooming on the bar, because there is no bar card. Since the flowering on the bar means self-touching, it is not self-touching.
Please note the following points:
1, don't make color cards.
For example, there are four or five cards in a deck, including one pair, four or five cards in ten thousand cards, and the remaining two or three cards are bags and strips, so I want to mix all the colors. No matter what I encounter, I will make up my mind to pack, stripe and even split. This is hard work, and the result is mostly thankless.
2, think more about the possibility of doing other things, don't just stare at making a color card.
For example, it doesn't matter whether you match a color card or not. There is a break and a break. Let nature take its course and don't be too greedy. Because others don't mind being calm and decisive, making a color card will soon become the target of public criticism. So coveting 1 or more, twice is likely to make the bigger cards that could have been drawn in vain.
3. If you have touched a plate with 4, or have a treasure card in your hand, you don't have to stick to color mixing.
Especially when others can soon find out that you are making monochrome cards, we suggest that you'd better give up making monochrome cards and find a shortcut to combine cards. If you are a dealer, give up making monochrome cards. This practice is by no means a loss, but a retreat.
