This article takes the four handed down Chu Gong Jia bells and the Chu Gong Jia bell unearthed in Zhouyuan as the research objects, and combines the existing research results to conduct a comparative study of the two from the perspective of inscription glyphs, word relationships, style, and decorative patterns. It is pointed out that the inscriptions, style, and word relationships of Chu Gong Jia bells in the late western Zhou dynasty all show the regional characteristics of the Chu characters. The inscriptions, style, and relationship between words of the Chu Gong Jia bell unearthed in the Zhou dynasty also reflect the regional characteristics of the western Zhou dynasty. This article also conducts a comparative study of the bird patterns on the bells of the western Zhou dynasty, and points out that the bird patterns on the Chu Gong Jia bell unearthed in Zhouyuan are not common in the southern region during the western Zhou dynasty, but are more closely related to the Baoji Phoenix bird pattern with a fleshy crown common in the Baoji region during the western Zhou dynasty. Its stiff demeanor and forked upturned tail may be due to improper imitation of southern bird patterns. The regional characteristics and bird pattern on the right drum of the Chu Gong Jia bell inscription unearthed in Zhouyuan indicate that its origin or locality is in Zhouyuan. The research in this article has a promoting effect on the understanding of the regional characteristics of bronze inscriptions in the western Zhou dynasty, and is beneficial for us to further understand the early Chu characters and Chu culture. The conclusions of this study can provide some reference for the formation and development of the character system in the Zhou dynasty and the study of the casting and circulation patterns of bronze.

The modern Chinese copula, 是 shì, had not yet appeared in the oracle bone period. It began to emerge in Zuozhuan (左傳 ), and appeared only when expressing the judgment of complex topics. Based on the observation as such, this paper looks into the demonstrative of 是 shì, and examines its evolution before it becomes a copula. The task takes three steps: first, usages of 是 shì are investigated throughout various time periods; second, characteristics of sentences containing 是 shì are explained according to how it is used; and last, a comparison is made of sentences containing 是 shì in excavated Chu manuscripts in order to determine their properties. What can be, in fact, explained through the analysis of Chu bamboo literature in the Warring States Period (475-221 BC) are the characteristics of the transitional sentence before the development of 是 shì into the copula. First, in the bamboo slips “Sande” from the fifth volumes of “Chu bamboo slips collected in Shanghai Museum”, the object prepositional phrase appears, indicating the transitional phase in which the 是 shì phrase in the first stage advances toward the second one. “Sande” is the literature of the late Warring States Period, and has a V writing section in which the object has been transposed and no '也' has appeared at the same time. Second, apart from the situation in which the first stage is used as a subject, the situation in which the explanation part leads to NP/N fixation can be considered through the object transposition leading to the NP/N fixation of the topic part. Last, given that “邾公華鍾 (哉(載)公眉壽 ，邾邦是保 : Tsp, NP是 V)” is an article of the Spring and Autumn Period, it is estimated that 是 shì had been initially regarded as the object, and the phrase “TNP, NP＋是＋VP/V” was gradually used as a fixture through the process of the analogy and re-analysis. However, it is critical that this view be examined more closely, and therefore, further research is also needed.
