Many dictionaries which are published in China like Xiandai Hanyu Cidian, Xiandai Hanyu Guifan Cidian, Xiandai Hanyu Fenlei Cidian, Dangdai Hanyu Cidian, Xuesheng Xiandai Hanyu Cidian and others. define “shangxin” is an adjective, many other dictionaries like HSK Ciyu Yongfa Xianjjie, Hanyu Jiao yu Xue Cidian, Zhongchao Cidian, Shiyong Hanyu Yongfa Cidian and others. argue that “shangxin” is a verb. When “shangxin” has the same function and meaning in the sentences, Ii can not be both of an adjective and a verb. therefore l argue that the word classification of shangxin” is in need of study. “Shangxin” in modern chinese belongs to “liheci”. The so called “liheci” is king of verbs, not adjectives. According to my study, verbs can be divideded into intransitive verb and transitive verb, and “liheci” is basically an intransitive verb. So l argue that “shangxin” is not an adjective , but an intransitive verb. In modern chinese, some “liheci” can also have objects, for examples “danxin”, and “shangxin”. So l can say that “shangxin” has double classification of intransitive and transitive verb. When “shangxin” is an intransitive verb, its meaning is “neixin beishang, tongku”, and when it is a transitive verb , it has the meaning of “yin.......neixin beishang, tongku”.
