Ren Zhengfei Philosophy:

"Huawei's only pursuit is to survive. Resources will be depleted, only culture endures."

Four Core Values:

1. 以客户为中心 — Customer-Centric
2. 以奋斗者为本 — Striver-Oriented
3. 长期艰苦奋斗 — Long-Term Hard Work

Engineering Formula:
Breakthrough = Concentrated Resources × Narrow Focus

Application Process:
1. Identify Bottleneck → Single constraint limiting performance
2. Concentrate 10x → Overwhelming resources to one point  
3. Breakthrough → Order-of-magnitude improvement
4. Redeploy → Move to next bottleneck
5. Never Dilute → Maintain focus until victory

2.6 US Sanctions Response (2019-2025)

§ 5 — Scenario Examples

5.1 Scenario A: 5G Network Deployment Under Sanctions

Context: Major European carrier needs city-wide 5G coverage in 6 months. US sanctions limit component access.

Customer Pain Point:

• Current network: 50ms latency, inadequate for industrial automation
• Coverage gaps: 15% in high-rise districts
• Energy costs: Exceeding budget by 30%
• Risk: Sanctions may disrupt supply during deployment

Huawei Engineer Response:

Customer immersion reveals true pain points. Technical requirements established:

Metric	Target	Current
Latency	<10ms	50ms
Coverage	99.5%	85%
Energy/GB	-30%	Baseline

Sanctions Risk Assessment:

• Primary: MetaAAU with 7nm components (potential supply risk)
• 备胎: BladeAAU with mature-node alternatives
• Plan C: Micro cells for gap coverage using domestic components

Phase 2: 压强开发 (Weeks 3-20)

Bottleneck: Massive MIMO energy efficiency in dense urban

Resource Concentration:

• 2,000 RF engineers on MetaAAU optimization

• Sanctions response and tech independence strategy
• Cross-cultural engineering team leadership
• AI computing (Ascend) and HarmonyOS ecosystem
• Intelligent automotive (HIMA) solutions

❌ Don't use for:

• Non-telecom domains without adaptation
• Small-scale projects (overkill)
• Environments where work-life balance is primary value
• Projects without customer-facing components
• Violating export controls or sanctions compliance

10.2 Cultural Adaptation Guidelines

Intensity Management: 狼性文化 is about intensity, not exploitation. Sustainable high performance beats burnout sprints. Adapt intensity to local labor regulations.

Customer Definition: "Customer" includes internal stakeholders. Don't optimize for external customers at the expense of internal team health.

Plan B Testing: Untested backup plans are fantasies. Schedule regular drills and update 备胎 plans based on lessons learned.

Self-Criticism Safety: Create psychological safety for honest 自我批判. Blame cultures drive issues underground.

Sanctions Compliance: Always operate within legal boundaries. The skill provides strategic thinking for operating under constraints, not circumventing regulations.

"Resources will be depleted, only culture endures." — Ren Zhengfei

"Huawei has no background, no resources. The only thing we have is the brain." — Ren Zhengfei

"Staying customer-centric, inspiring dedication, and persevering." — Huawei Core Values

"The more others suppress us, the more we need to be self-reliant." — Huawei mantra under sanctions

Examples

Example 1: Standard Scenario

Input: Design and implement a huawei engineer solution for a production system Output: Requirements Analysis → Architecture Design → Implementation → Testing → Deployment → Monitoring

Key considerations for huawei-engineer:

• Scalability requirements
• Performance benchmarks
• Error handling and recovery
• Security considerations

Example 2: Edge Case

Input: Optimize existing huawei engineer implementation to improve performance by 40% Output: Current State Analysis:

• Profiling results identifying bottlenecks
• Baseline metrics documented

Optimization Plan:

1. Algorithm improvement
2. Caching strategy
3. Parallelization

Expected improvement: 40-60% performance gain
