How to identify the authenticity of gold?

There is really a method to test by "biting", but it is not recommended. Although the higher the purity of gold, the deeper the bite marks, the lead-plated gold is also very soft and can also be bitten. On the contrary, the method of using ceramic scratches is more reliable. When using unglazed ceramics, you only need to gently scratch the gold product. The scratches black are fake, and the gold is real.

"I think I'd better send it to the store." Lin Yinghua was not very confident in her ability to distinguish gold.

"If you don't have enough, ask me if you want it." The gold Wu Miaomiao gave him was not a pound, but a pound, and he just took it to exchange for money.

"Aren't you afraid that I will run away with you?" Lin Yinghua asked her when she went out.

Wu Miaomiao glanced at him: "Master-Servant Contract."

Lin Yinghua: "..." Damn, I forgot this thing again!

How many grams of gold per pound? 500 grams.

The price of gold changes every day. The price he exchanged at that time was 375 yuan/gram, which means he exchanged for 187,500 yuan, and rounded it up to about 190,000 yuan. Lin Yinghua had never received it for so many years in her life, and she was a little dazed and could not believe it.

He took the bank card that he had just checked and had transferred money in, and went straight home.

However, on the way back, he had already thought about it and reported a few thousand yuan less at that time, and said that he had only exchanged for 180,000 yuan. The remaining money was considered the "hard-working money" left for himself.

"Do you know how much I changed?!" said excitedly as soon as I entered the door.

When he was not around, Wu Miaomiao rechecked her backpack and took out the book and studied it carefully.

"How much?" She didn't care about this at all, and didn't even raise her head.

"180,000. Oh my god?! I have never gotten so much money in my life. Look, my hands are still shaking now..." He took out his bank card and shared this joy and excitement with her.

I thought he was exhausted and only had a salary of about a hundred yuan a day, and only a few thousand yuan a month. The rent was only enough for food. As a result, the God of Wealth gave him a bag of gold ingots, and he exchanged it for almost 190,000 yuan?! How long does it take for him to save so much money to save? Even if the 7,500 yuan he deducted, he would have to save it for two months without eating or drinking.

"oh."

Compared to Lin Yinghua's excitement, someone was too calm, as if a bucket of cold water was poured on his head: "Why do I feel that you don't seem to be very happy?"

Wu Miaomiao finally raised her head and asked him unhappily: "Your name is Lin Yinghua, right?"

"Yes, what's wrong?"

"Did you lose something the day you met me?"

"What? No..."

"Think about it."

"I feel like nothing is lost," Lin Yinghua started rummaging on himself. As he flipped through, he realized, "The bracelet left to me by my mother is gone."

What she was talking about was such an indifferent thing? Wu Miaomiao had a cold face, hooked her fingers, and asked him to come over.

Lin Yinghua felt the danger, but she still walked over obediently.

Unexpectedly, as soon as she arrived in front of her, she pressed her on the bed and beat her up directly.

Lin Yinghua screamed: "Ah... Help! I was wrong, I really knew I was wrong, it was 187,500 yuan, not 180,000 yuan, wuwu... I was just too poor. If I wanted a little money, I deducted 7,500 yuan. I didn't dare to deduct too much. Really, I swear... I deducted that little bit..."

Wu Miaomiao raised her eyebrows: "There is still this? You are so amazing, and you dare to hide your private money on your back?"

"I dare not, I dare not, really, I will never dare to do it again."
