Buying or artificially increasing followers on Douyin (TikTok China) through third-party services like "众人业务网" is strictly against Douyin's Community Guidelines and Terms of Service. Such practices carry significant risks:

• Your account may face restrictions (e.g., shadowbans, limited reach), temporary suspension, or permanent banning.
• Fake followers do not contribute to genuine engagement (likes, comments, shares), which is critical for long-term growth and monetization on the platform.
• It damages your account's credibility and trust among real users and potential collaborators.
  For legitimate growth of your Douyin followers, focus on these strategies:

1. Create high-quality content: Tailor videos to your target audience's interests (e.g., tutorials, entertainment, niche expertise) with clear visuals and engaging storytelling.
2. Post consistently: Stick to a regular schedule (e.g., 3-5 videos/week) to keep your audience engaged.
3. Use relevant hashtags: Mix popular (high-volume) and niche (low-competition) hashtags to increase discoverability.
4. Engage with your audience: Respond to comments, collaborate with other creators in your niche, and participate in trending challenges.
5. Leverage Douyin's features: Use live streams, duets, stitches, or effects to interact with followers and expand your reach.
   Genuine growth takes time, but it builds a loyal, active audience that adds real value to your account. Avoid shortcuts that harm your long-term potential. If you have further questions about legitimate Douyin growth, feel free to ask!
