We should spend time to read/discuss trading related books/subjects only.
If you do not agree with other's opinion, you may either ignore his post or tell him how you feel about it in polite tone/with a diplomatic manner. Everybody has right to talk, but not with dirty words.
If you need help from HH, please do not scare them away.
i.e. Please do not attack/abuse others.
God bless Daqian
