In this paper, 35 Tupaia blangeri chinensises (TBCs) in Shanghai Cancer Institute that were captured from Kunming,Yunnan province and their offspring that were born in the laboratory are used. We analyze hereditary conditionally index about some shape characters, observe their behavior rules in 24 hours ; dissect to study the structure; study the living habits of the wild TBCs in course of mating, gestation, and lactation; measure the changes of body weight and figure type of G1 TBCs, summarize the changes during the domestication .The results show that:1. According to Rife-Burnaamanas law, We analyze the appearance characteristic with hereditary conditionality including color of fur, orbit etc.. We think that wild fur with seasonal red spot, white fur of abdomen, non-white orbit, fleshcolor palm, non-cocked ear, round tip tail, and the line between breast of both sides is in a vertical position with axis line.2. Almost all the motility activity of TBCs are in daytime. Their behavior in 24 hours are obvious orderliness.3. Compare 7 TBCs specimens in different age, we find amounts of lumbar vertebra, sacral vertebra and caudal vertebra between 7 specimens are different.4. Reproduce is not seasonal any longer after being domesticated. Their gestational period is about 6 weeks and in second week, the body weight is reduced, but from then on, the body weight gains day after day. Their lactation period is 5 weeks, intake of nutrition component is more than the TBCs in rest. Before weaning, the difference on body weight and figure type between bottle-fed TBCs and breast-fed TBCs is significant, but when their bodies are mature, the difference are not significant.5. With age, the body weights and figure type of G1 generation are increasing continuously and sex maturity of TBCs is 3 or 4 month age. Their body mature is 6 month age, after that their body weight and figure type have no obvious change. Body weight and figure type are imitated by cubic curve. It is significantly relationship between body weight and the figure type.6. With the increasing of domestication time, some wild habits of TBCs change. Compared with their parents, G1 generation likes to conversant with human being and their sensitiveness to stimulate outside reduces.
