Very interesting how china seems to always want to create "monster" pairs, for them good is not enough. zheng siwei used to be actually quite good when partnering with CQC, although it's undeniable that they often lost to tontowi/natsir, CHN then overhauled this pair by pairing ZSY with HYQ, the result was a "monster created". Likewise with Wang Chang, when partnering with Di Jian they often had trouble facing Leo/Daniel, finally CHN paired Wang with Liang, and it seems that so far their strategy has worked, Liang/Wang is progressing to become a new monster. Even though there were also some of their experiments that failed, at least they showed they had the courage to change their top pairs to look for the best, this coupled with the large stock of quality players at the CHN camp, it's no wonder that they always dominate major badminton events now and in the future. Just my 2 pences.
