Chang Sheng (easy to understand)
Chang Chen or Chang Ling Chen Yun (Chen hour corresponds to your BB’s birth time of 8:50 as Chen hour, and Ling Chen Yun represents BB’s future growth into a person above the clouds) A noble gentleman)
Chang Yu (Yu represents water chestnut, and Chang is a homophone for long, so Chang Yu means that your BB will have a very outstanding performance in the future)
Chang Geng Or Chang Yin (2010 is the year of Geng Yin, but the combination of Geng and Yin is not good-sounding, so I separated it as a name)
In addition: Chang Haowen and Chang Qing are also good choices
