Subject + 压 + Object
The verb 压 (yā) means "to press," "to push down," or "to weigh down" and describes applying downward force or pressure on something. It is versatile and appears in many compounds and figurative expressions. In economic contexts, 压低 (to push down/lower) is a common extension, as in 压低价格 (push down prices).
