I remember that there was a god on the Internet who speculated that in Love of the Hawthorn Tree, the death of the third child was due to a radioactive substance.

"Lao San" contracted the disease while helping out at the "Second Mine". In the movie, it is mentioned through a conversation with an old miner that a miner died of the disease some time ago. Later, "Lao San" also collected some stones and sent them to the provincial capital for inspection.

Modern science tells us: Uranium in stone can be absorbed by bones and bone marrow through the dust produced during its processing, and its decayed alpha particles can cause kidney damage; radium in dust is an alkaline earth cation and is easily When replenishing the calcium in the bones, it is brought in, causing bone cancer; in addition, the radon that decays into the radium destroys the bone marrow, causing leukemia.

Radon is produced by the decay of the radioactive element radium and is the only natural radioactive inert gas in nature. It is colorless and odorless. According to reports, 8% to 25% of the total number of lung cancer deaths worldwide are caused by previous inhalation of radon in the air. Among them, there are about 30,000 to 40,000 people in the United States, about 7,000 in the United Kingdom, and about 7,000 in Sweden every year. Hundreds of people, Russia and China have about 50,000 each.

In recent years, it has been discovered in Sweden, the United Kingdom, the United States and other countries that radon can also induce various leukemias. Henshaw, a British medical scholar who studies leukemia, conducted a survey in 14 countries and concluded that 12% of leukemias in the UK are caused by radon. Some reports also believe that radon can also induce kidney cancer, skin diseases, melanoma, and cause damage to bone marrow.

In "The Love of the Hawthorn Tree", the "third child" died of leukemia in the end. The cause of his illness was probably radon radiation in the ore. Under radon radiation, although not all miners will develop leukemia due to different personal constitutions, the chance of developing leukemia will increase significantly.

The "third child" is undoubtedly the most unfortunate one among them. His tragic fate has been irreversible since he met "Jingqiu".

Because, in order to see his most beloved girl, he often took the initiative to go to the "Second Mine" to help in exchange for the opportunity to take a break. In this way, he had time to go to the city to see "Jingqiu".

As long as he often goes to the "Second Mine", he will be exposed to radioactive ores, and it will be a matter of time before he contracts leukemia.

So, "Lao San" and "Jing Qiu" are a destined love tragedy. They were not destined to be together.
