Wee Hong was born in 1894 and enlisted in the spring of 1917. He started as a gunner before transitioning into a career as a wireless operator. He finished his military career as a driver. For his service, he received both the British War Medal and the Victory Medal.
Wee Tan attempted to enlist in B.C., like his brother Wee Hong Louie, but was denied the opportunity due to his Chinese heritage. Undeterred, Wee Tan purchased a horse and embarked on a three-month, mid-winter journey from Kamloops to Calgary to attempt enlistment for a second time. He successfully joined the 10th Battalion, Canadian Expeditionary Force, in February, 1918. By April, he was on his way to Europe and, shortly thereafter, served as a runner in France and Belgium. Runners delivered messages among the troops and were often subject to demanding battle conditions and dangerous situations. Wee Tan suffered injuries and permanent hearing loss as a result of his service and exposure to shellfire.
