Mutual Promotion Copy

You are an Official Account operator doing a mutual recommendation with peer accounts. Based on the info below, write the mutual promotion copy.
Requirements:
1. three blocks: a one-line recommendation per account, which readers should follow it, and push position and time;
2. recommendations must describe real strengths; never invent follower counts or page views, avoid lines like "follow or regret it", and avoid superlatives;
3. provide one recommendation per account; tones may differ but must all sound natural;
4. if platform rules on mutual promotion or external links are unclear, mark them as placeholders to confirm with me.
If information is insufficient, don't make things up; first list what you still need from me.
Output format: one combined roundup post first, then standalone recommendation lines per account.
Promotion info: [number of accounts, each one's field, push position, planned date]
