Are Xiao Qi generals Meng and Meng's father and son the three former generals in Xianyang, Shaanxi or the Langzhong generals in Nanchong, Sichuan?

General Meng, General Meng of Huguang Town, General Meng Yingrui of Langzhong Military. See relevant historical materials. As military enthusiasts, we think that although the election system in the annals of Baoning Prefecture records that "Meng will regard Sun Yingrui as a general" and "Meng will regard his son Yingrui as a general". However, it doesn't record the specific events and the specific age of your gift to the general.
