Watermelon keeps its sweetness and sound.

Although this word is not necessarily correct, it can be read directly. Don't be unclear, I am in a province and city, and so is Shenyang.

Bao Tian sells watermelons. 1990 to 2000 In my city, many people selling watermelons shouted like this. Generally, there are two ways to sell, one is guaranteed sale, and the other is optional sale.

Self-selection means that people who buy melons choose a melon by themselves, and then weigh and give money to let the melon leave. This self-selected watermelon has a low price per catty, but it may choose raw melon eggs. After buying a melon, you can't go to the merchant to return it. You are what you choose.

Guaranteed telephone means that the watermelon seller will choose a watermelon for you and will only ask you the size after selection. After the buyer agrees, the watermelon seller will draw a piece on the watermelon with a knife and show it to the buyer with a knife to prove that the watermelon is ripe. If the watermelon is raw, throw it aside and show it to the buyer until it is ripe. The price per catty of this guaranteed watermelon is more expensive than the watermelon you choose.

So at that time, people who didn't choose watermelon basically promised to buy watermelon, so although they spent a little more money, all the melons they bought were ripe.

Besides, as mentioned above, Bao Tian is called Bao Tian, and some people call Bao Tian and Sha Qi. It means that all the melons here have been cut for you to see. Watermelons without raw melons are all ripe. Shaking means that the melons are ripe. It's equivalent to boasting.
