[Bug] mermaid syntax does not display properly

### Bug Description

mermaid syntax does not display properly
Below is the sample text

### How to Reproduce

According to the system thinking method, I will disassemble the problem structure from multiple dimensions, analyze the characteristics of the elements, and provide a systematic solution:

---
### **Problem structure decomposition**

1. **Core concept layer**

- Pale blue dot (Earth's cosmic position)

- Philosophy of science (the impact of cosmic perspective on human cognition)

2. **Content expression layer**

- Text logic (there is a semantic break in the original text)

- Accuracy of key data (such as the vague expression of the number of galaxies)

3. **Emotional transmission layer**

- The sense of awe caused by the scale of the universe

- Reflection on the meaning of human existence

4. **Communication effect layer**

- The universal value of Carl Sagan's views

- The resonance intensity of popular science texts

---
### **Key element analysis**

| Element name | Characteristics | Advantages/limitations |

|-----------------|-------------------------------|------------------------------|

| Pale blue dot image | Visualized cosmic perspective | Concrete philosophical proposition, but data support is needed |
| 4 billion stars | Sense of scale | The actual number should be 100 billion stars in the Milky Way |
| "Dust" metaphor | Strengthening human sense of insignificance | Oversimplifying the hierarchical structure of galaxies |
| Science-Humanities Link | Cosmology reflects existentialism | Logical ruptures in the original text weaken the appeal |

---
### **Systematic problem diagnosis**
```mermaid
graph LR
A[Text expression defect] --> B(Wrong expression of the number of galaxies)
A --> C(Semantic rupture destroys immersion)
D[Lack of thought depth] --> E(Failure to extend Sagan's anti-narrowism claim)
F[Communication efficiency bottleneck] --> G(Lack of contemporary reality relevance)
```

---
### **Systematic solution**
1. **Concept calibration plan**
- Correct astronomical data: The Milky Way has about 200-400 billion stars → The earth is "a speck of dust in a galaxy of 200 billion stars"
- Supplementary galaxy level: The observable universe contains 2 trillion galaxies (ESA data in 2025)

2. **Logical reconstruction plan**
```markdown
New structural chain:
1. Blue dots taken by space probes → 2. Data on the proportion of total cosmic matter → 3. Sagan's original quote:
"Our pretentious arrogance is particularly ridiculous in the universe"
```

3. **Philosophy deepening plan**
- Add three-dimensional dialectical relationship:
| Cosmic scale | Human response |
|----------------|-----------------------|
| Physical insignificance | Uniqueness of civilization (life, consciousness) |
| Short time | Breakthrough in cognition |

4. **Communication enhancement design**
- **Current connection points**:
* Climate crisis (the sense of community of destiny for all mankind living in the blue dot)
* Progress in deep space exploration (2025 Europa life detection mission)
- **Multimedia transformation suggestions**:
Make a blue dot size comparison interactive model (Earth-Solar System-Milky Way-Virgo Supercluster)

**Value of system thinking**: Through the paradoxical connection between the cosmic perspective (grand) and individual existence (subtle), scientific and humanistic qualities are cultivated in cognitive impact - when humans truly understand the essence of "dust on the blue dot", they can transcend nihilism and sublimate into a profound sense of responsibility for the survival of civilization.
