G, if I follow correctly, BS=balance sheet item, which you say has already been paid. Amount paid you note of 176,333 RMB is YTD in 2021 (not full annual period).
As of June 30, 2021
176,333
However, the screenshot I posted includes these amounts for full years 2017-2020 as well, which you didn't mention, but which I assume were also paid. Top of table also notes RMB '000
As of Dec. 31,
2017 2018 2019 2020
108,503 123,431 141,405 166,357
So this sums to 716,029 (RMB'000) or 716,029,000 RMB ~US$106,250,000.
It appears these are milestone payments that have been paid to date, even pre-launch.
