I copied a bit of the calm teacher's background, and my perspective is: 1. Abstract enough, a group of Chinese people output poor English to Chinese listeners on space, which is quite meme; 2. The probability of being a pure scammer is relatively low (not non-existent), otherwise we could have directly cheated earlier; 3. Anyway, I only got 1 sol. If I make a profit, I can brag, but if I lose, I'll only lose 1 sol A thousand words, I just want to copy the SOL chain from a few front end teachers
