After six months in Manila, Wallace was asked to make sales and service calls in the more remote regions of the territory. He traveled to Hong Kong, Macao, Canton, finally settling in Shanghai for six months. He became fascinated with Chinese history, art and culture. He admired the jade carvings of all colors, shapes and sizes, but mostly loved figurines of people and animals. He maintained this interest in Chinese art throughout his life. He began collecting jade and his collection was seen covering every surface in his office; he never tired of sharing their beauty.
