Is it possible to get a Business (F) Visa at the chinese embassy in Bangkok?

Is it possible to get a Business (F) Visa at the chinese embassy in Bangkok? I will work for a period of 5 months in China but I will be travelling the 3 months before my entry. I am from Belgium. Even so, if this is not possible can I ask someone of my family to apply for me (in Belgium) and send it to me (Bangkok, or somewhere else?) If yes, where would it be safe to send it to (a Belgian embassy, a Chinese embassey, etc.)?

I will be travelling from start of April en plan to arrive in China start of July.
