The xiongnu empire rose in power and trade even after the chinese attempted to block its influence by:

Sent princesses to Marry Xiongun leaders.

Explanation:

At first, China tried to block the advance of Xiongnu Empire by miltary force, but they failed  and they had to use one of their last resorse tactics: Arrange marriages with the enemy. They sent princesses to Marry Xiongnu important leaders along with gifts to ecourage them to stop their attacks; even the daugther of the emperor was offered for marriage. It was useful to set a peace treaty between the Chinese and the Xiongnu  which kept the Xiongnu as allies for decades, however it was very costly for China as they had to sent gifts constantly and accept trading conditions more benefical for the Xiongnu. At the endgame, the peace was broken when the Xiongnu attacked again now stronger in power and trade.

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.

the first 10 amendments to the u.s. constitution are known as the bill of rights. those 10 amendments establish the most basic freedoms for americans including the rights to worship how they want, speak how they want, and assembly and peaceably protest their government how they want. the amendments have also been subject to much interpretation since their adoption, particularly the right to carry a gun under the second amendment.

"a bill of rights is what the people are entitled to against every government on earth, general or particular, and what no just government should refuse, or rest on inference," said thomas jefferson, the author of the declaration of independence and the third president of the united states.
