Teacher: Now, understand the problem? Solve this instance: Authorities in the central province of Quang Ngai Wednesday rescued a father and son who have been living up a tree house in the jungle for more than 40 years. 
  
 It took many hours and around 40 kilometers through the jungle for the officials to reach the men’s place, which had been found by some of their family members. 
  
 The father, Ho Van Thanh, 82, was too weak to walk and some men had to carry him out of the jungle on a hammock. 
  
 First investigations found Thanh had fled into the jungle bringing his son Ho Van Loan, then around one year old, during a panicking night in 1971 in the Vietnam War, when his house was bombed, killing his wife and two older sons. 
  
 They lived in a house that looks like a bird nest, built from sticks on a big tree around six meters from the ground, and near a stream. 
  
 They used dry bark to make pants, though officials found Thanh has carefully kept a little red coat of his son and his soldier’s trousers at a corner of the house. 
  
 The two also made their own tools like knives, axes and arrows for hunting. The tent on a tree that Ho Van Thanh and his son Ho Van Lang had been living for around 40 years in the jungle 
  
 Daily foods include cassava, corn, and wild leaves. They have a field of nearly one hectare (2.47 acre) that also plants sugarcanes. 
  
 Both have forgotten the mainstream Kinh language. 
  
 Ho Van Tri, Thanh’s youngest son who was newly born on the bombing day, found his father and brother more than 20 years ago but he could never persuade them to come home, according to a report by news website VnExpress. 
  
 Tri said some relative had saved him that day. 
  
 With an uncle’s help, he camed to find his father and brother in the jungle 12 years later. 
  
 He has been bringing them salt and oil every year but they have not accepted him yet. 
  
 He said many times he brought more people to help bring them home but they would hide quickly anytime they saw people. 
  
 Ho Minh Lam, Thanh’s nephew, said people have brought clothes and pots for him to use but he just kept them in a bag. 
  
 They kept a small fire in the house and smoked tobacco they planted themselves to keep warm on cold days.

 A local newspaper reported that they wore loincloths made of bark and used a homemade axe to chop down trees for firewood. They survived on corn that they had grown, plus fruits and cassava roots from the jungle. 
  
 Inside their treehouse home, five metres in the air, the pair kept a stash of arrows for hunting and knives for killing animals. 
  
 But there were poignant mementos of their previous life.

 The father kept his soldier’s trousers neatly folded in a corner. Beside them was the little red coat his son was thought to have been wearing when they fled. 
  
 Vietnamese media tracked down another son of Mr Ho senior – a man named Ho Van Tri, who said that he discovered his father and brother 20 years ago, but had not been able to persuade them to return to modern society. 
  
 He said he brought more people to see them in the jungle to help bring them home – but they would hide quickly whenever they saw anyone approaching. 
  
 The pair were said to be barely able to communicate with outsiders, with Mr Ho junior only knowing a few words of the local dialect of the Cor ethnic minority group, while his father had fallen out of the habit of speech. 
  
 They were discovered by a party of local people who were travelling through deep forest in Tay Tra district of Quang Ngai province, in central Vietnam. 
  
 Photos published on a Vietnamese website showed the elderly Mr Ho being carried out of the forest on a stretcher, surrounded by curious villagers. 
  
 The Vietnamese district authorities have confirmed that Ho Van Thanh once lived a normal life with his family in the commune’s Tra Kem hamlet. They suggested that he was probably driven by shock when he took his young son and ran into the jungle after the mine explosion wiped out the rest of their family. ||||| The older man could communicate a little in the Cor ethnic minority language, but his son only knew a few words, an official at Tay Tra commune in Quang Ngai province said on condition of anonymity. 
  
 Ho Van Thanh was last seen running into the woods with his then-infant son Ho Van Lang after a bomb exploded in his home, killing his wife and two other children in 1973, newspaper Dan Tri reported. 
  
 They were discovered when two people from a nearby village ventured 40 kilometres into the forest looking for firewood and spotted the two men’s treehouse. The villagers reported the find to local authorities who recovered the pair on Wednesday. 
  
 The two men survived by cultivating forest vegetables and hunting animals. They had no contact with the outside world, the report said. 
  
 Photographs in local media showed the younger man with dishevelled hair wearing a loin cloth made from tree bark. |||||
Student:
After a bomb killed Ho Van Thanh's wife and two of his sons during the Vietnam War, Ho took his 1-year-old son into the jungle—and never came back. That was 40 years ago. On Wednesday, officials carried the too-weak-to-move 82-year-old away from the treehouse he and his son had been living in, Thanh Nien News reports. Ho and his son, Ho Van Lang, now 42, have spent the intervening years hunting and subsisting on both wild plants and cassava roots and corn and sugarcane grown on their own nearly 2.5-acre field. The men wore loincloths made of bark—though the elder Ho still had his military uniform pants folded neatly in the treehouse, which sat about 16 feet off the ground, alongside a small red jacket his son once wore. The younger Ho knows only a few words, and his father has "fallen out of the habit of speech," the Telegraph reports. Though Times Live reports they were found by villagers who were searching for firewood and alerted authorities, their existence apparently wasn't entirely unknown. Ho's youngest son—who was a newborn when Ho disappeared— found the two more than two decades ago, but couldn't persuade them to accept him or rejoin society, despite annual gifts of salt and oil. (Amazingly, they're not the only family to live in isolation for 40 years.)
