1, altered tape (you can deduct the altered tape if you don't want to erase it)
2, correction fluid (used too much will become a big lump)
3. Tape (first use correction fluid, then change the tape, and finally feel that tape is the best, but you can't stick it in the same place too many times).
4. Fading liquid (usually used to clean the handwriting on clothes)
5. rubber bands are not allowed to be taken during the exam ... you can scrape them off with a knife, just like the principle of adhesive tape.
