# Post-Fair Follow Up: The 48-Hour Window
You collected 50 business cards at the Canton Fair. You fly back to New York, sleep off the jet lag, catch up on a week of missed emails, and finally decide to email the Chinese factories a week later to ask for a quote.
You receive zero replies. Why? You missed the window.
> **💡 Withyou Trip Expert Verdict:**
> "In Chinese manufacturing, speed is everything. The ultimate rule is the **48-Hour WeChat Window**. A factory sales rep spoke to 300 foreign buyers during the fair. By next week, they will completely forget who you are. You MUST send a WeChat message to the rep while you are still sitting in your Guangzhou hotel room, explicitly referencing a detail from your conversation (e.g., 'We talked about the red silicone handle'). Do not wait for email."
## 1. The Follow-Up Communication Matrix
| Channel | Response Rate | Speed | Verdict |
| :--- | :--- | :--- | :--- |
| **WeChat (Voice/Text)** | ⭐⭐⭐⭐⭐ (95%) | 🟢 Instant | **The only way to do business in China.** |
| **WhatsApp** | ⭐⭐⭐ (50%) | 🟡 Fast | Requires the factory to use a VPN. Unreliable. |
| **Email** | ⭐⭐ (20%) | 🔴 Days | Ignored, caught in spam, or buried under 1,000 others. |
| **Phone Call** | ⭐ (10%) | 🔴 Instant | Language barrier makes phone calls disastrous. |
## 2. How to Structure the Perfect WeChat Message
Do not just say "Hello, send me price." You must trigger their memory and show you are a high-value buyer.
* **Step 1: The Visual.** Send the photo you took of their product *with* their business card in the frame.
* **Step 2: The Context.** "Hi Sunny, this is John from the US. We met at Booth 14.2 A05 today."
* **Step 3: The Actionable Request.** "I am ready to proceed with a sample order. Please send the PI (Proforma Invoice) for 5 units of Model #X77 via email to john@company.com, but confirm the tracking number here on WeChat."
## 3. The "Silent No" vs. The Inbox Purge
If a factory does not reply to your WeChat message after 3 days, it means one of two things:
1. **The Silent No:** Your requested MOQ was too low, and they don't want to lose Face by explicitly rejecting you, so they ignore you.
2. **The Inbox Purge:** Their WeChat is exploding with messages from 500 buyers, and you got pushed to the bottom.
* **The Fix:** Send one polite "bump" message: "Hi Sunny, just following up on the sample order." If they ignore that, move immediately to your backup supplier.
## ❓ Frequently Asked Questions (FAQ)
**Q: Should I wait until the entire Canton Fair is over to follow up?**
A: Absolutely not. The best time to follow up is that same evening from your hotel room. The factories are taking notes at night; if you message them immediately, you go to the top of their priority list for the next morning.
