回复：做博士后的朋友请给个建议

Be careful and be patient when pick your first offer. If you pick up a wrong boss, life gonna be miserable. On the other hand,a good adviser can really help you out, both to your future career and to your personal issues. I will suggest to find a nicer and honest one instead to take risk with your current option who shows lack of capability to even keep jis own words! Good luck!
