    Hearing this, Cheng Qiheng nodded and said: "That's right. I have bought a piece of goldware with sulfide attached to it before. Using conventional methods, no acid, alkali or complexing agent can remove the rust."

    "Then how did you solve the problem?" Wang Menghan asked.

    Cheng Qiheng chuckled and said, "I'll just leave it alone if I can solve it any other way."

    Wang Menghan rolled her eyes at him: "Don't you know how to ask others, or use your own brain to check some information?"

    Cheng Qiheng chuckled and said: "When I was in school, I never learned chemistry well. I got a headache when I saw chemistry. The key is that there weren't many attachments on the goldware, so it wouldn't have any effect if I left it alone, so I didn't do it.  "

    "You're just lazy!" Wang Menghan turned his head and asked, "Dad, is there anything you can do?"

    Wang Zhixuan did not answer, but asked Meng Zitao with a smile: "How do you think it should be handled better?"

    Meng Zitao thought for a while and said: "I remember that sulfide can oxidize the sulfide ions produced in the dissolution reaction into elemental sulfur in the presence of oxidants, destroying the dissolution balance. So, if the dissolution reaction continues, is  Isn¡¯t it possible to dissolve all the sulfide on the surface of gold?¡±

    Cheng Qiheng said incredulously: "No, you even know this? Don't tell me, this is also in the information Mr. Zheng gave you."

    Meng Zitao shook his head: "That's not true. It's just that I'm not taking the self-examination now, so I just read some basic chemistry materials."

    "Uh" Everyone then remembered that Meng Zitao had said before that he would take the self-examination, but there was no news after that, and he never heard Meng Zitao mention it, so he forgot about it. Unexpectedly, he actually put it into practice.

    "You are really good." Cheng Qiheng gave Meng Zitao a thumbs up, and then said: "By the way, I remember our city's self-study exam. I have already passed the exam in April, but you didn't take it?"

    Meng Zitao said: "I didn't feel confident this time, so I didn't go and applied for July."

    Cheng Qiheng said with a smile: "Then do I want to wave the flag and cheer for you?"

    "Okay, I'm not afraid of embarrassment anyway." Meng Zitao said with a smile.

    Cheng Qiheng touched his nose: "Well, then I'm really going."

    Meng Zitao said with a teasing smile: "Then go, no one will stop you, so be sure to bring a banner with you."

    "That's definitely no problem." Cheng Qiheng felt that he had jumped into a trap, and immediately changed the topic: "Let's talk about your golden bowl."

    Wang Zhixuan laughed and said, "I think Xiao Meng's suggestion is quite good. You can give it a try."

    Meng Zitao said: "Uncle Wang, please do me a favor."

    Wang Zhixuan said: "Okay, you can go to the Shanghai Stock Exchange with peace of mind and I will help you handle it."

    Meng Zitao smiled and cupped his hands: "Thank you, Uncle Wang."

    "Zitao, here!"

    As soon as Meng Zitao came out of the train station exit, he saw Yu Weigang waving to him, and Meng Zitao walked over quickly with a smile.

    After getting in the car, Meng Zitao asked: "Shall we go to the hospital now?"

    Yu Weigang nodded and said, "Would you like to go to the hotel to settle down first?"

    "Okay, let's buy some gifts by the way." Meng Zitao then asked, "How is the work here?"

    Yu Weigang said: "The jewelry store is still under preparation. Let's just work like that. Basically, we just need to follow the steps."

    "No one is trying to make trouble with you, right?" Meng Zitao asked again.

    Yu Weigang chuckled: "There will always be villains, but I haven't dared to jump out yet. Don't worry, they are all clowns, so there is nothing to be afraid of."

    Meng Zitao chuckled: "If you need my help if you need anything, just ask."

    Yu Weigang smiled and said: "Then I will definitely not be polite."

    After going to the hotel to put away their luggage and buy gifts, Meng Zitao and the others took a car to the hospital where Mu Yueze was treated.

    After asking the nurse the location of the ward, the three of them went to the elevator of the inpatient department and waited for the elevator.

    While waiting, a pretty and pleasant young woman in her early twenties stood next to the two of them, carrying a thermos box.

    After a while, I saw a middle-aged couple walking over quickly. The woman yelled at the young woman with an annoyed look on her face: "You are actually here!"

    The young woman looked a little flustered, but she calmed down immediately: "Dad, Mom, why are you here?"

    The woman said angrily: "You still have the nerve to ask, we still want to ask you, if you don't work hard, what will happen to you?"Thank you so much. You can just rest and recuperate. Don't worry about money.  "

    Mu Yueze smiled bitterly and said: "It will cost at least more than one million to cure my disease. Do you think I can stop worrying? The key is to cure it. I can no longer act like a normal person and can only do some simple tasks."  .¡±

    For patients with acute leukemia, before the condition is relieved, the patient's ability to live and work will be greatly affected due to the disease itself or the impact of chemotherapy.  The patient at this time is unfit for work.  But when the condition is completely relieved.  If the patient's physical strength allows, some work within his ability can be considered.

    Meng Zitao smiled and said: "Hey, what do you have to worry about? With two bosses like us here, why are you worried about not being able to find a suitable job for you?"

    Yu Weigang patted his chest and promised, "That's right, the work is all on us. Your most important task now is to work with peace of mind."

    After listening to what the two said, Mu Yueze asked curiously: "What business are you doing now? Are they all antiques?"

    Yu Weigang said: "I am now in the jewelry business. As for Zitao, there are many industries under his name, including antique shops, auction companies, foundations, and laboratories. Soon he will set up a factory. After all, there is one  Suitable for your job position?"

    Mu Yueze looked very surprised: "I didn't expect that Zitao, you would have changed so much after not seeing each other for a few years." (Remember the website address: www.hlnovel.com
