First of all, I think the main problem is that trees attract the wind. Han Han has been eyeing him since he came from Taiwan Province Province. Later, many people began to aim at Liu Qian. In fact, the main reason is that Liu Qian got angry too quickly. At first, he existed as a bridge to improve cross-strait relations, so he was allowed to attend the Spring Festival Gala. However, some Liu Qian began to expand rapidly because of his success. If you watch carefully, you will find that Liu Qian is good at hyping himself, which is normal in Europe and America, but it is not recognized by the public in China. Therefore, with the opposition of the first person, it is normal for the next person to start opposing Liu Qian.
Secondly, the most important thing is that Liu Qian knelt before the Japanese emperor, which angered many netizens. Liu Qian is also a public figure, and he is also the representative of China. As a result, he knelt down to people from other countries, which was detrimental to China's face, so people who opposed him naturally began to increase again. The growth of his fame was given to him by the state, but he died himself.
Liu Qian was able to catch fire, mainly because it was a bridge between Chinese mainland and Taiwan Province Province, so he started to catch fire. But kneeling down to the Japanese emperor is bad for China people's face, so he has disappeared now.
