Wei Zi committed suicide seven times.

According to the information you provided, Ren Sheng and the killing of seven people in Shanghai need specific eight-character comprehensive analysis to give a more accurate answer. Here are some possible scenarios:

1. Wei Ziqi was killed in Shanghai, indicating that the fate of the Lord is relatively good and he can accumulate certain wealth and social status. At the same time, the fate of the Lord is determined and decisive, with decision-making power and execution power, but it is also easy to be too impatient and impulsive. It is necessary to learn to control emotions and calmly deal with problems.

2. If other factors of fate are weak, such as the absence of five elements and the weakness of the yen, it may affect the personal ability and career development of fate. You need to improve your ability through continuous study and hard work in order to have better development and achievements.

3. If other factors are strong, such as heavenly stems and earthly branches's combination of five elements of life. It means that fate is developing well and it is easy to get success and wealth, but we also need to pay attention to avoid being too complacent and complacent and keep a modest and diligent attitude.

It should be noted that fate is only one aspect that affects life, and the development of life is also influenced by many other factors, such as family, education and social environment. Therefore, we can't make an absolute judgment on life just by fate, we need to explore and develop in practice.
