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

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)

1. 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
