On the outskirts of Beijing, there is a vast, deserted cave that contains an enormous number of species of cave gecking dinosaurs.
They are not endangered but they are not very well known, as the Chinese government does not want to tarnish its image as a conservationist.
It is estimated that there are at least a few hundred of these tiny, green-eyed creatures in captivity around the world.
Their populations have declined by more than half over the last decade.
One reason for the decline has been over-hunting and poaching, which has resulted in the disappearance of a third of the species.
The government is currently negotiating with China’s own wildlife authorities to return some of these creatures to their wild habitats, as well as allowing some to be released to the public.
A new film, released by China’s National Geographic Society on Thursday, aims to bring some of the creatures to life and share their stories.
The story is a heartbreaking tale of survival and perseverance, with many of the animals rescued from captivity being given the opportunity to live their lives in public.
The creatures’ stories are not uncommon, and some of them have gone on to find a life in other countries.
For example, the Chinese cave goliath, which measures more than 15 metres in length, is still a highly sought-after pet in the US.
The giant tortoise is a favorite among American hobbyists and collectors.
In 2016, a team of Chinese conservationists released a group of giant tortoises into captivity.
They were taken by a team from the State Forestry Administration of China and placed into two cages in the mountains of Qingdao in eastern Yunnan province.
The first cage had a wooden frame, while the second was constructed from bamboo.
At the time, the team had been given the task of releasing the animals to ensure their health and wellbeing.
The team brought the animals from the wild to Qingdax, where they were kept in an artificial hot and humid environment, and at the same time, a specially designed ventilation system.
When the team arrived, they found that the reptiles were alive and well.
The team was able to check on them for four days, including a day when they were under the care of a veterinarian.
Once they were back in the cage, the animals were immediately tested for disease and were then allowed to eat.
After this initial trial, the veterinarians decided to release the animals back into the wild.
But when they returned, the reptiles had been released from their cages and were free to roam the landscape.
The next day, the veterinarian was shocked when the animals began to run around the outside of the cage.
He immediately ordered the cages to be removed and the animals allowed to roam free.
There were also other signs that the animals had recovered.
The animals had not started to run up the sides of the cages when they had been put into them.
And when the cage doors were opened, the creatures could be seen wandering around freely.
At the end of the day, when the team returned the animals, they had a good idea of the extent of their recovery.
The majority of the reptiles still had visible scars from previous surgery, and they also had a lot of food scraps scattered around.
As the team was working on the project, the local authorities began to raise awareness about the importance of conservation in China, and after a number of positive reactions, they decided to let the reptiles be released into the public as well.
According to a local news outlet, the release was attended by representatives from the Ministry of Forestry, the Ministry for Natural Resources and the National Parks Administration of Yunnan, as a way to educate people about the reptiles’ plight and to bring the species back to its natural habitat.
Since then, the captive animals have been kept at Qingdazian National Park, and the government has promised to give them the opportunity again.
