On December 31, 2008 (December 5, 2008 in the lunar calendar), the first-instance verdict was pronounced in the melamine incident in Sanlu milk powder. Since March 2008, Sun Xizhao, a urology surgeon at Nanjing Gulou Hospital, has successively received samples of 10 urinary stones from Nanjing Children's Hospital. This kind of baby caused by drinking Sanlu milk powder is very common in a Beijing hospital. At this time, Wang Yuliang, former deputy general manager of Sanlu, learned of the matter. Sanlu has been receiving similar complaints from consumers since the end of 2007. Sanlu, who discovered the problem, has been communicating "quietly" with consumers. In the evidence presented by Sanlu Group to the court, it was found that it had paid a total of 1.18 million yuan in child examination fees. This has nothing to do with the cost of inspecting children after Sanlu stopped production. However, the situation at that time did not make Sanlu realize the huge danger, because it was not until mid-May 2008 that this issue was submitted to the Sanlu management team meeting. Tian Wenhua said in her confession that in May, case reports had begun to show an upward trend. Sanlu went to the hospital at that time to understand the situation, but it could not prove that the kidney stones in the child must be caused by Sanlu milk powder. Areas with high incidence of stones and little drinking water can all cause stones to occur. According to Tian Wenhua, there were many people attending the management team meeting at that time, including the general manager, deputy general managers, some directors and two consultants. The meeting decided to establish several groups, Wang Yuliang was responsible for quality inspection, and Hang Zhiqi, former deputy general manager of Sanlu, was responsible for strengthening milk source supervision. The meeting "required each group to start work immediately, hold meetings every two weeks, listen to reports from each group, and solve problems immediately." Tian Wenhua said in her confession. After entering July, reports of "baby stone" cases have entered a period of high incidence. In a hospital in Lanzhou, Gansu Province, 16 infants with kidney stones were admitted in the first half of the year. Most of them were 5 to 11 months old. The sick children were seriously ill, and some children had developed renal dysfunction. Cases have been reported in Jiangsu, Shaanxi, Shandong, Anhui, Hunan, Hubei, Jiangxi, Ningxia, Hebei, Shanghai and other places. This has attracted more and more attention. One night in mid-July, a senior executive of Sanlu was questioned by a well-known technical expert from a ministry background, whether Sanlu had added something to cause the incident in Gansu? His answer is: Big companies don't. Subsequently, more and more cases were reported in various places, and one case was reported to have died in Gansu. Unnamed related reports also began to appear in the media. "I am getting more and more anxious, so I asked them to find an authoritative organization to check." Tian Wenhua said. Submit for inspection in July: Samples submitted for inspection must be kept confidential. According to Sanlu technical cadre Li Zhaoxu, in late July 2008, he went to the office of his boss Wang Yuliang, who was preparing to send the samples to Beijing for inspection. A few days ago, they went online to discover news that pets died from eating melamine dog food in 2007. Li Zhaoxu told Wang Yuliang that there is no need to go to Beijing, the Inspection and Quarantine Technical Center of Hebei Entry-Exit Inspection and Quarantine Bureau in Shijiazhuang can inspect. So, Li Zhaoxu began to contact testing matters. The next day, Li Zhaoxu and another technical cadre, Zhang Zhiguo, submitted for inspection. Wang Yuliang specifically instructed that this matter must be kept secret. Therefore, Sanlu products were not written on the inspection package. When registering, they claimed that they were samples taken from the market for counterfeiting and raw milk obtained from Shandong and other places. On July 26, 2008, after preliminary testing, it was found that melamine did exist, and Li Zhaoxu informed Wang Yuliang of the news. The 31st inspection report has been officially formed. However, the inspection party requires information such as the name of the product manufacturer, otherwise no report will be given. After some coordination, Sanlu received the test report on August 1. On August 1, Zhang Zhiguo, who was on a business trip, heard about the report through his colleagues. His reaction was: Tell another technical cadre quickly and report it to Wang Yuliang. Colleagues told him that Wang Yuliang had learned about the matter. In the evening, he received a phone call from Wang Yuliang: Come back quickly. On August 2, after receiving the notice, he rushed to Shanghai to purchase kits. By that time, all senior officials of Sanlu Group had spent a panicked night. On August 3, Sanlu milk powder was stopped. On August 5, Sanlu resumed producing small-package milk powder and passed the test on August 6. However, Sanlu has never stopped the production of liquid milk products. Tian Wenhua's reason is that he does not want Sanlu to lose too much. However, there is a lot of market pressure to exchange goods with qualified products. On August 12, Tian Wenhua and others discussed melamine safety standards. Tian Wenhua suggested setting it at 15 mg per kilogram, and Wang Yuliang suggested setting it at 10 mg per kilogram. This resulted in the formation of Sanlu's safety standard. On August 13, Sanlu Group held an expanded meeting of its management team and determined a replacement plan to exchange products with lower melamine content for higher products. Participants in the meeting included more than a dozen Sanlu senior executives. On August 15, Sanlu's board of directors meeting was held. Tian Wenhua confessed that the foreign party did not request public disclosure, but was just worried. At this time, a director put forward a reason, and the board members responded positively. One director said: "This is a good reason. You can do this." Tian Wenhua also believes that foreign parties fully participated in the management of the Sanlu milk powder incident and should bear responsibility. Our reporter contacted Fonterra many times, and Fonterra expressed its reluctance to provide comments. On August 18, Sanlu Group issued a recall notice. Within a short period of time, they recovered 17.95 million yuan worth of milk powder from consumers and 260 million yuan of products from distributors. But these did not prevent Sanlu from dying. In the face of the continuous exposure of "stone baby" cases, Sanlu has been weaving lies to cover up everything. On the morning of September 11, Sanlu related people also stated that Sanlu's products were qualified and refused to disclose the truth about melamine that they had known more than 40 days ago. On the evening of September 11, the truth about Sanlu melamine came to the world. On September 17, Tian Wenhua was detained on criminal charges and began more than three months of "reflection". In the early morning of December 31, Tian Wenhua met Wang Yuliang, who was carried off the car on a stretcher. He had previously jumped off a building and attempted to commit suicide out of guilt. Tian Wenhua suddenly burst into tears. In the court, she recalled everything in the past, was "heartbreaking and miserable" and expressed "willingness to accept the punishment of the law." With the news that Sanlu was about to go bankrupt, Tian Wenhua, former chairman of Sanlu, also went to court on the last day of 2008. Also appearing in court were Wang Yuliang and Hang Zhiqi, former deputy general managers of Sanlu Group, and Wu Jusheng, director of the raw milk business department of Sanlu Group.
