"Soon" is a very elastic concept in these types of pieces out of China.
After the People's Bank of China left LPRs unchanged last week I saw ANZ saying they expect an RRR cut in Q4 of 2021, and another in Q1 2022 and that the MLF and will be the tools used to inject long-term liquidity (interest rates will be used as the primary tools of monetary policy). This is at least a little more helpful than "soon".
