All Focus on A shares and H shares

HK stocks(H share) and Shanghai stock(A share) price difference become bigger and bigger after recent A share soaring, the H shares aren't following up actually. So the next thing i expected is the H share will be next to catch up. Same comapny if H share is cheaper than A share, which one will you buy? Money will always flow to where it got better opportunities.
