1. First of all, you can express your recognition of each other's work by inviting you to dinner as a small reward.
2. Understand the completion of the work, and if it has been completed, check the acceptance results. If it is not completed, you can further consult the reasons and help find out the problem.
3. Ask the other party how things are going at present and whether there are any difficulties in this process.
4. Appropriate use of words to ease the atmosphere and make the conversation easier.
5. If you don't know the specific extrapolation process, you can ask the other person, for example, "What is the extrapolation process of this position?" Or "How long does this interpolation take to complete?"

Through such communication, we can not only understand the progress of the internal push, but also help the other party to finish the work better.
