I will definitely scan and email the receipts to my dad. But whom will he show the receipts to when he arrive in Guangzhou?
-I just think the $400 may have included the security surcharge, so you may check the NVC letter to see what kind of fee this $400 was for (the old security surcharge might be $70.00). You may also call NVC to confirm whether your payment of $400 included the surcharge fee. If no, your dad may pay the fee to US Consulate in Guangzhou, See:

7. 我可以在那裏繳納簽證費用？
所有的移民申請人需要繳納其相應類別的簽證處理費。 大部分的申請人都是在檔案轉到廣州前直接遞交到美國簽證中心。 如果部分申請人在麵試前還未繳費， 可在麵試時，在我館的出納窗口遞交。
