# Chinese Lottery Predict

Analyzes historical data from major Chinese lottery websites to provide statistical predictions for the next draw.

## Prerequisites

- **WebSearch**: To fetch the latest lottery results.
- **Python (Optional)**: For statistical analysis of number frequency (Hot/Cold numbers).

## Workflow

### 1. Input Parsing
The user will provide:
- **Lottery Type**: e.g., "双色球" (Double Color Ball) or "大乐透" (Super Lotto).
- **Funds** (Optional): Budget for the purchase (default: "10元").

### 2. Data Retrieval
Use `WebSearch` to find the latest 30-50 draw results.

#### Search Strategy (Anti-Scraping & Reliability)
1. **Primary Search (Official Sources)**: Attempt to fetch data from official government or authoritative industry sites first.
   - **Keywords**: `site:cwl.gov.cn {Lottery Type} 往期`, `site:lottery.gov.cn {Lottery Type} 开奖公告`, `site:500.com {Lottery Type} 走势图`
   - **Target Domains**:
     - `cwl.gov.cn` (China Welfare Lottery - Official for Double Color Ball)
     - `lottery.gov.cn` (China Sports Lottery - Official for Super Lotto)
     - `zhcw.com` (China Lottery Online)
     - `500.com` (500.com)

2. **Fallback Search (Static/Portal Sites)**:
   - **Trigger**: If official sites fail to load content (due to dynamic JS rendering or anti-scraping blocks) or return incomplete data.
   - **Action**: Search for static news portals or text-based lists which are easier to parse.
   - **Keywords**: `"{Lottery Type}" 近50期开奖结果 汇总 新浪`, `"{Lottery Type}" 历史号码 文本版`
   - **Target Domains**: `sina.com.cn`, `163.com`, `sohu.com`.

#### Data Verification
- Cross-reference the latest draw date from at least two sources to ensure data is up-to-date.
- Ensure the "Issue Number" (期号) is continuous.

### 3. Data Analysis
Analyze the retrieved data to identify:
- **Hot Numbers**: Numbers that appeared most frequently in the last 30 draws.
- **Cold Numbers**: Numbers that haven't appeared in a long time.
- **Omitted Numbers**: Current omission count for each number.

### 4. Prediction Generation
Generate 1-5 sets of numbers based on a mix of Hot and Cold numbers.
*Disclaimer: Lottery draws are independent random events. Predictions are for entertainment only.*

### 5. Output Generation
Generate a report in Chinese using the following format.

#### Output Template
