I thought I'd tackle it... alas, I don't know Chinese. I think I'll look for some Ottoman Sultan who could do something similar...
My preliminary notes for Kangxi timeline:
1654 - Kangxi Emperor is born. Zhou Zhang begins his experiments.
[POD]
1667 - Kangxi's coronation at the age of 13.
1672 - Kangxi, aged 19, learns of Zhou Zhang's experiments, half a year after Prince Yinzhi is born. Yinzhi (later Prince Zhi) is Kangxi's fifth son, but the first who looks as though he'd survive infancy - first four have died early. [as per OTL, except for the experiments]
1673 - State Princess Rongxian is born. She is the first daughter to survive infancy, after two other girls.
1674 - Changhua, the emperor's sixth son, dies as an infant. Yinreng, the seventh son, is born. Duanjing, the girl no. 4, is born. [butterflied away an infant]
1675 - Changsheng, the seventh son, is born.
1676 - When it becomes obvious that Changsheng is sickly and will not live much longer, the Emperor (aged 23) orders that his new consort has to come from a family known for having healthy children. At the end of the year, a suitable woman is found in the Magiya clan.
1677 - Yinzhi (later known as Prince Cheng), the eight son, is born. The other Yinzhi, future Prince Zhi, is five years old. [I butterflied one son in-between away]
1678 - Yinzhen, the ninth son, is born.
1679 - Yinzan, the tenth son, is born. Kejing, daughter no. 5, is born.
1680 - When Yinzan dies as an infant, his mother, Concubine Tong, is sent away. Yinzhi (Prince Zhi) is eight years old. Yinqi and Yinyou are born. [Yinzuo, who died in infancy IOTL, butterflied away]
1681 - Yinsi, son no. 13, is born.
1683 - Yintang, son no. 14, and Yin'e, son no. 15, are born. A sixth daughter, Wenxiang, is born. [butterflied away another boy infant and two girl infants who died early due to better family planning]
1685 - Yinzhi (future Prince Cheng) is eight years old and he shows great promise. Prince Zhi is 13. The Emperor (now 31) believes Zhang Zhao's findings are true. Yinzi (son no. 16) is born. Chunque, daughter no. 7, is born.
1686 - Yintao, son no. 17, and Yinxiang, son no. 18, are born.
The Emperor announces Zhang's findings as Eight Blessed Principles and orders all high-ranking officials to adhere to them.
1688 - Yinzhen, later renamed Yinti, (no. 19) was born. Wenke, daughter no. 8 and the last one, is born. [2 infants butterflied away]
1690 - Princess Quejing, daughter no. 9, is born.
1691 - Princess Dunke, daughter no. 10, is born.
1693 - Yinwu (no. 20) is born. [butterflied an infant away]
Prince Zhi's eldest son, Hongyu, is born. [pure assumption, based on the fact Zhi is 21]
1695 - Yinlu (no. 21) is born. The emperor is 41. He creates Blessed Rank Offices. From now on, they record all children and their parentage. All nobles are segregated into one of the classes, depending on mental and physical capabilities, regardless of family ties. Prince Zhi is 23. Prince Cheng is 18.
1697 - Yinli (no. 22) is born.
1704 - Fifteen years after the noble class has been ordered to obey Eight Blessed Principles, Emperor Kangxi (aged 47) receives first reports on the first generation of Blessed Children. He finds roughly 2/3rds of them match the expectations. Scholars are ordered to continue Zhou Zhang's experiments in order to find out what is lacking in the remaining 1/3rd.
1706 - Yinyi (no. 23) is born. [butterflied away 2 boys in-between]
1711 - Yinxi (no. 24) is born.
1712 - Yinhu (no. 25) is born. The Kangxi Emperor is 47.
1714 - Yinqi (no. 26) is born.
1716 - Yinmi (son no. 27 and the last) is born.
