單方面的監管是不足夠的，我們必須雙管齊下。 Not just one side, but both sides of the fence.
如此雙管齊下，就有可能服大地主大資産階級的投降危險爭取時局的好轉前途。 If we do both these tasks simultaneously, we shall be able to overcome the danger of capitulation by the big landlords and the big bourgeoisie and to bring about a turn for the better in the whole situation.
雙管齊下，長期存在的科技與經濟脫節的問題，有可能得到比較好的解决。 When both reforms are carried out, we shall perhaps be able to solve the longstanding problem of the separation between science and technology and the economy.
雙管齊下 to do two things simutaneously in order to attain an objective.
