Since your IP address indicates you're in Henan, I was able to make direct frequency contact with another station in Henan previously.
1. Can you recommend any nearby simulated repeater stations?
2. If there are no repeaters available, you can go directly to frequency 438.500.
3. Go to a higher location (such as the top of a building; if you're at the top of a building, the range should be around 100 km).
4. If you can't connect, try practicing letter-based explanations and doing practice exercises (to build a foundation for future "B" level learning)...
