the numbers are 差价倍数, because most of things are much cheaper in China. Laozhong didn't give actual allocations to different categories, so it is not possible to know the actual expenses.
But roughly, if we assume the 差价倍数 is average 5-8x, then laozhong actually spent 162/(5~ = 32~20+ 万美元. Again, if assuming 7.7 average exchange rate, Laozhong spend about 35~22万 RMB a year
