We report the discovery of four new open clusters (named QC 1, QC 2, QC 3 and QC 4) in the direction of Cygnus Cloud and select their members based on five astrometric parameters (l, b, ϖ, , μ_δ ) of Gaia DR2. We also derive their astrophysical parameters for each new cluster. Structure parameters are generated by fitting the radial density distribution with a King’s profile. Using solar metallicity, we performed isochrone-fitting on their purified color-magnitude diagrams (CMDs) to derive the age of the clusters. The known cluster NGC 7062 in an adjacent area is chosen to verify our identification process. The estimated distance, reddening and age of NGC 7062 are in good agreement with the literature.

我们报告了在天鹅座云方向发现的四个新疏散星团（命名为 QC 1、QC 2、QC 3 和 QC 4），并根据五个天体测量参数（l、b、ϖ、、μ _δ ）选择它们的成员盖亚DR2。我们还为每个新星团推导出它们的天体物理参数。结构参数是通过用 King 剖面拟合径向密度分布来生成的。使用太阳金属丰度，我们对其纯化的色等图 (CMD) 进行了等时线拟合，以推导出星团的年龄。选择相邻区域中已知的星团 NGC 7062 来验证我们的识别过程。NGC 7062 的估计距离、变红和年龄与文献非常吻合。
