Okay. So, in general, total CapEx, including everything, including wafer, cell and module, but in terms of allocating the key investment allocation is in mono wafer and PERC cell. For the module capacity, we increased from 10.8 gigawatts to 16 gigawatts, but the majority of our 80% incremental power is from the increased output is not new capacity. We just add very small scale, roughly, 1.2 gigawatts new capacities for the module, the CapEx is very small, but for the remaining parts, roughly 4 gigawatts is throughout our upgrades increment, increased output, decreasing bottleneck on production. And for the bifacial capacity, in general, our existing PERC cell capacity, we can do the bifacial, and in, for some facilities, we just need to do a very small, small, minor agreement, minor upgrades to make sure the capacity can do this bifacial products. So, it's, it's, I think it's very, very small, even though the CapEx.
