我明白你的意思，我们在没有生产以前，很多数据都不清楚，很难计算下一步的

I understand what you mean. Before we had production, many data were not clear and it was difficult to calculate the cost of the next step. But I can guarantee that the products I help you produce are very low-cost and must be of high quality, because Those jobs have known me for a long time, they are small in scale, so the cost is relatively low

I see what you mean, we didn't produce before, a lot of data is not clear, it is difficult to calculate the next cost, but I can assure you that the products I help you produce are very low, and certainly high quality, because those jobs and I have known for a long time, they are small, so the cost is relatively low
