With the process of human conquest of nature, there are fewer and fewer uncultivated lands on land, and even the area of African rainforests and Amazon rainforests is decreasing, and species are dying every day. Although there are still species on land that have not been discovered by humans, they are mainly concentrated in some small animals, such as various arthropods, and large animals that have not yet been discovered are already rare.

But the ocean is different.

About 70% of the earth's surface area is covered by oceans, and the blue ocean contains a large number of unknown mysterious creatures, especially the strange creatures of the deep sea are beyond people's imagination. Scientists point out that humans don't know as much about the deep ocean as they do about the surface of Mars.

Zhang Zi'an understood what Rena meant.

Thousands of new marine species are discovered every year, and the vast majority of them have unknown populations, perhaps only the one that was discovered, maybe a few million, everything is possible, and it cannot be rashly included in the international list of endangered animals until it is investigated, so it is not protected by law, which has room for maneuver.

In China, cats and dogs account for almost 90% of the pet sales market, while in Germany it may be less than 10%, but the German pet market is far more developed than he imagined. From Rena, he saw a way to find a way to find a different way even without relying on cats and dogs.

Zhang Zi'an also considered fish before, after all, fish is also a very important pet, but Binhai City, as a coastal city, does not belong to the fish-poor area, and there is no shortage of fish - in the summer, go to the night market, find a food stall to sit down, and eat seafood for twenty or thirty yuan until you vomit.

There are a few aquariums in Marina City, but most of them are dismal, mainly selling tropical and cold-water fish wholesaled from Gwangju and Jinmen. There are three major fish distribution centers in China - Guangzhou, Tianjin, and Anshan, and Anshan is Anshan.

With these aquariums as a lesson from the past, Zhang Zi'an has never made up his mind to take the route of the aquarium.

The area on the second floor is very large, but relatively speaking, the aquarium area occupies a relatively small area, but the reptile area occupies the largest area, perhaps one is that the Germans prefer reptile pets, at this time there is a little boy about twelve or thirteen years old wandering in front of the glass box of rhinoceros iguanas, and the second is that these pets themselves need more space.

When an adult male customer from Asia had a problem communicating with the clerk, Rena said sorry to Zhang Zi'an and went over to deal with the matter first.

Zhang Zi'an was idle anyway, and when he looked back, the elves were also attracted by the strange-shaped pets in the store, so he followed over to see how Rena was doing business.

When he got closer, he found that Rena's staff was very hospitable, but she was not proficient in professional things, and she couldn't answer customers' questions, probably because there were so many pets in the store, if she could do all of them, she would probably be a zoologist.

The Asian customer has a crush on a ball python and a terrarium and is ready to pay, but the clerk stops him from buying the terrarium, and the two get into an argument. He doesn't speak German and doesn't speak English well, which leads to communication problems.

Noting that the Asian customer was holding a phone with a Chinese brand and a familiar WeChat icon on the home screen, Zhang tried to ask, "Hello, is it Chinese?"

"Yes, are you the clerk at this store?" said the Asian customer, like a savior.

"No, I'm here to travel. Zhang Zi'an said, "Have you encountered any problems?"

"That's right, I want to buy this ball python, and by the way, I will buy this terrarium again, but this clerk is so arrogant that he won't let me buy it, and he has to let me buy another more expensive terrarium!" The customer said angrily: "I didn't expect that there are also forced buyers and sellers in Germany! Can you help me complain about him?"

He chose a golden desert spider ball python and a very ordinary terrarium, and fiddled with the ball python in the palm of his hand, like a person who is very used to playing with snakes.

Fina stared coldly at the ball python, as if she might tear it in half at any moment.

Zhang Zi'an hurriedly waved his hand to Fina secretly, signaling it to calm down, if it really attacked the ball python, it would get out of its stealth state, and it had to frighten the people around it.

Most ball pythons have a gentle temperament, are not aggressive, are not poisonous, and do not hurt people.

Zhang Zi'an looked at it a few times, but he didn't see anything wrong with the snake and the breeding box, and he didn't understand why the clerk didn't let him buy it, so he relayed the problem to Rena in English.

Reyna pointed to the instructions on the ball python's glass case and explained to the customer, "I'm sorry, sir. The ball python you chose is 55 cm long, while the terrarium you choose is 100 cm long. German law stipulates that the minimum length of the terrarium inhabited by reptiles cannot be less than twice the length of the reptile. The terrarium you chose earlier is too small for us to sell to you. Either you choose a smaller ball python or a larger terrarium. ”

After she finished speaking, she took a copy of the code from the service desk on the second floor, opened it and let them read it. The Code contains illustrated texts detailing the instructions for keeping reptiles and the relevant legal provisions.

Zhang Zi'an relayed her words to him in Chinese, and at the same time cleared the doubts in his heart.

After figuring out the reason, the customer was still not satisfied, but there was no way, since he was on someone's territory, he had to abide by the rules of others.

With Zhang Zi'an's help, he changed to a larger breeding box, and bought heating pads, lamps and lanterns in the box, water basins, and bedding materials laid in the box. The price of the Desert Spider Ball Python is 399 euros, and the price of the terrarium and various accessories adds up to more than 300 euros, but it is still much cheaper than having a cat and a dog.

When paying, Rena handed over a document to the customer, the first page of the document is the price, type, size, origin, scientific name and other relevant information of the ball python, the customer needs to fill in his name and passport number and other personal information on the second page, and the third page is full of legal terms and disclaimers, which is very crowded. Compared to this document, the pet sale agreement in Zhang Zi'an's store is like a pediatric.

This customer probably couldn't read the German on the third page like Zhang Zi'an, so he glanced at it casually, filled in the information and paid.

He didn't have a good impression of this store, but he was grateful to Zhang Zi'an for helping him clear up the misunderstanding, and Zhang Zi'an said very generously that everyone is Chinese and helps each other when they go out.

Rena was also relieved that when the Berlinale opened, there were always customers who did not understand the language.
