Over the following years, Zhang engineered and executed a number of diplomatic plots against Chu, supported by the constant military raids on Chu's northwestern border. Chu suffered many defeats in battles against Qin and was forced to cede territories to Qin. King Huai I of Chu was furious and ordered a military campaign against Qin, but he was tricked by Zhang Yi into breaking diplomatic ties with his allies, and his angered allies joined Qin in inflicting a crushing defeat on Chu. In 299 BC, King Huai I was tricked into attending a diplomatic conference in Qin, where he was captured and held hostage until his death. In the meantime, Qin launched several attacks on Chu and eventually sacked the Chu capital city of Chen (陳; present-day Jiangling County, Hubei

In the next five decades after King Huiwen's death, King Zhaoxiang of Qin shifted his attention to northern China after Qin's victories in the south against Chu. In the early years of King Zhaoxiang's reign, the Marquis of Rang (穰侯) served as Qin's chancellor and he actively pushed for military campaigns against the Qi state

 in the far eastern part of China. However, the marquis had his personal motives, as he intended to use Qin's powerful military to help him conquer a fief in Qi territories, since the lands were not directly linked to Qin and would not be under the Qin government's direct administration.

Subsequently, King Zhaoxiang's foreign advisor, Fan Sui, advised the king to abandon those fruitless campaigns against distant states. King Zhaoxiang heeded Fan's advice and changed Qin's foreign policy to adopting good diplomatic relations with distant states (Yan

. The conflict at Changping was deemed as a power struggle, as both sides pitted their forces against each other not only on the battlefield, but also in the domestic context. Although Qin had an abundance of resources and vast manpower, it had to enlist every man above the age of 15 for war-related duties, ranging from front-line service to logistics and agriculture. King Zhaoxiang of Qin even personally directed his army's supply lines.

. Subsequently, the Qin forces marched on the Zhao capital city of Handan in an attempt to conquer Zhao completely. However, the Qin troops were unable to capture Handan as they were already exhausted and also because the Zhao forces put up fierce resistance. King Xiaocheng of Zhao offered six cities to Qin as a peace offer and King Zhaoxiang of Qin accepted the offer after being persuaded by Fan Sui. Within Zhao, many officials strongly opposed King Xiaocheng's decision to give up the cities and subsequent delays caused the siege on Handan to be prolonged until 258 BC. Meanwhile, Bai Qi was consecutively replaced by Wang Xi, Wang Ling and Zheng Anping as the Qin commander at the siege.

In 257 BC, Qin was still unable to penetrate Handan after besieging it for three years, and Zhao requested aid from the neighbouring states of Wei

The Qin forces crumbled and retreated and Zheng Anping surrendered. The combined forces of Wei and Chu continued to pursue the retreating Qin army and Wei managed to retake part of its original lands that were lost to Qin earlier.

One of these texts was Master Wu, written in response to a query by Marquis Wu of Wei
