Mentally handicapped refers to intelligence below the average line, such as a normal IQ of 90, below this line can be considered mentally handicapped. The slanted eyes and crooked mouth drooling on TV are not mentally retarded, but Down syndrome.

Liu Jun's technology before crossing can already screen Down patients in the fetal state, and the accuracy rate is very high, but many people are afraid of trouble and never do screening, but they regret it when they are born.

Liu Jun once accompanied the Fa Xiao's family after giving birth to a child to have a postpartum checkup, and met a pair of sisters in the hospital with a child with Down syndrome for a check-up.

The child was born to my sister, but my sister was holding me and communicating with the doctor, and the doctor was heartbroken and criticized them for not doing examination and screening, and my sister laughed there, and kept asking if there was a way to cure it, but my sister stood behind with a numb face.

Liu Jun was thinking at the time, the child will suffer for a lifetime, and this sister may be ruined for the rest of her life, why is her sister accompanying her, not her husband, and does the numbness on her sister's face have anything to do with her husband?

The reason for this terrible consequence is simply to save trouble and do a few fewer tests.

Another condition that also shows the characteristics of low IQ is the scholar syndrome, commonly known as rain man.

However, Liu Jun doesn't know what kind of situation 'Li Dajia' is, but he is definitely not mentally retarded.

Sister-in-law Osmanthus took Liu Jun's hand and said non-stop, thanking her for giving her family a chance to help the family, if it wasn't for kindness, no one would invite her to a family of three with two disabilities.

Liu Jun was polite for a while, and then unceremoniously arranged the work, and invited them to come over to work, Li Cripple was incapacitated, so he sat on the ground and made tiles with the people of Fujiang, while Osmanthus Sister-in-law and Li Da joined Liu Jun and Li Youwei, and moved tiles with mud together, and undertook the main physical work.

Sister-in-law Osmanthus works more than Liu Junlisuo, Li Da is even more powerful, his strength can top three adults, he was a little rusty at first, but soon he did better and better.

Liu Jun paid attention to the communication between Sister-in-law Osmanthus and Li Da from time to time, only to see that Sister-in-law Osmanthus first said a lot to him loudly, Li Da didn't react, so angry that Sister-in-law Osmanthus hit his hand hard, and then repeatedly told him that he would hit if he was in a hurry, and then showed him hand in hand, and the reaction was slow and hit.

The communication between Sister-in-law Osmanthus and Li Da is a standard stick education, but Li Da is too big, and Sister-in-law Osmanthus fights like tickling, and many times Li Da doesn't react at all.

After some difficult exchanges, Li Da finally understood what he was going to do, picked up the shovel and mud, turned it one shovel at a time, and soon became proficient, and could easily top three strong laborers.

With the addition of Sister-in-law's family, the progress has suddenly become faster, it took two days to make 500 tile embryos, and now it is made in one day.

All the prepared tile embryos are moved to the drying room behind the kiln and stacked, and after the kiln is fired, the mud embryos here can be dried at an accelerated pace.

After two days, the clay embryos accumulated to 1,500 pieces, enough to burn three kilns, and the first batch of tile embryos was completely dried in the shade, and it was time to open the fire for firing.

The stacking of tile embryos is a very skillful thing, this work can only be done by Li Youwei, after the tile embryos are placed, ignited, sealed kilns, and firing begins.

After an afternoon and a whole night of firing, and a day of cooling, it was not until the morning of the third day that the kiln could be opened, and when the pottery kiln was opened, Li Youwei's eyes couldn't help but light up as soon as he touched the tiles in his hand.
