t turns out that this little mechanism is hidden in the rice bag. No wonder it can't be opened all the time. It's a long way to learn! Is it difficult to open the sealing line when buying rice? There are many such examples, such as flour bags, cement bags, grain bags and so on. Today, I'll teach you a pithy formula. Just remember it, and it will be quick and easy to remove stitches in the future. First of all, we need to distinguish between "single line" and "double line". As the name suggests, single line means only one line. Remember, there is absolutely only one line on the rice bag. Double lines are two or more lines.

Pithy formula: single line to yourself, open to the right. One side of the single line faces itself, and then it opens from the right side of the bag. Use scissors or knife to directly disconnect the intersection of single line and double line. Then we first pull the thread of the double line, we will find that if we pull a little, we will not be able to pull it. Then, if we pull the single line again, we will find that the single line can be pulled out at once, and there is no dead line at all.

Once again, the formula is "single line to yourself, open to the right". As long as you remember this sentence, the rice bags and cement bags in the future can be opened directly without pulling the thread. In the end, you have to cut the bags.
