China has a long and complex history of political, economic, and educational shifts that have resulted in and from changing cultural values. Over time, the significance and format of social work education in China has changed, as has the need for professionally educated social workers that can support the ever-evolving social needs of China. To this end, some Chinese schools have begun to partner with schools in the U.S. to support the professionalizing of social work in China. This article presents the reflections of faculty and students involved in an exchange program for Chinese students to study in a U.S.-based master of social work program. Expectations, realities, needs, and recommendations of both faculty and students are discussed.

Objective: Solve the problems of poor positioning accuracy and low grasping success rate of the Delta robot in food sorting, and improve the robot's flexible grasping ability. Methods: Based on the existing binocular vision and delta robot technology, a flexible grasping method of delta robot based on binocular vision was proposed. Zhang Zhengyou calibration method was used to calibrate the camera, the target was identified and located by Hough transform at the chord midpoint, and the delta robot was controlled to grasp the dynamic target according to PID tracking and grasping. The feasibility of this method was verified by analyzing the performance of single target sorting and multi-target sorting. Results: This method can accurately, quickly and stably grab the target dynamically （success rate was above 94.0%）. Conclusion: The combination of binocular vision and delta robot can effectively improve the positioning accuracy of the robot and the success rate of sorting and grasping.

The Chinese government has relaxed many of the rules relating to university education. This will make it necessary for the state, individuals and universities to establish new roles and relationships. Many Chinese people aspire to a university education for their children, and are willing to save a large proportion of their income for this purpose. This has prompted some universities to introduce very high tuition fees. Others have lowered admission thresholds in order to obtain additional money from applicants who would not otherwise have gained entry.

The quality and grade of traditional Chinese medicinal herbs were assessed by their characteristics traditionally. According to traditional experience, the quality of the purple Flos Farfarae is better than that of yellow buds. NMR-based metabolomic approach combined with significant analysis of microarray (SAM) and Spearman rank correlation analysis were used to investigate the different metabolites of the Flos Farfarae with different color feature. Principal component analysis (PCA) showed clear distinction between the purple and yellow flower buds of Tussilago farfara. The S-plot of orthogonal PLS-DA (OPLS-DA) and t test revealed that the levels of threonine, proline, phosphatidylcholine, creatinine, 4, 5-dicaffeoylquinic acid, rutin, caffeic acid, kaempferol analogues, and tussilagone were higher in the purple flower buds than that in the yellow buds, in agreement with the results of SAM and Spearman rank correlation analysis. The results confirmed the traditional medication experience that "purple flower bud is better than the yellow ones", and provide a scientific basis for assessing the quality of Flos Farfarae by the color features.
