Qian Long was in high spirits, and talked and laughed as Commander Li Keshou waited on him. He had changed into an ordinary gown, while his bodyguards had also put on civilian clothes. Once at the lakeside, he gave his orders.

"He probably already knows who I am, but I want everyone still to pretend to be common people."

Imperial guard units had been hidden all around the lake with troops hand-picked by Commander Li behind them. Beyond the flickering lantern light, they saw five boats gliding towards them across the water. 'Leopard' Wei stood on the bow of the middle boat.

"I have been sent by Master Lu to invite Master Dongfang onto the lake to enjoy the moon," he announced, and jumped onto the bank and bowed before Qian Long.

Qian Long nodded slightly. "Excellent," he said, and stepped onto the boat. Commander Li, Bai and thirty or forty bodyguards boarded the boats with him. More than a dozen of the bodyguards were expert swimmers, and Bai ordered them to keep their wits about them.

They started out across the lake, which was a fairyland of lights. Pleasure boats were everywhere, bedecked with lanterns that filled the darkness like stars in the night sky and the sound of music floated across towards them. A small sampan darted into view then turned and led the boats to a flotilla of other craft. Despite the huge number of troops they had stationed around the shore, Bai and the other bodyguards were uneasy at the sight of such a powerful force, and all covertly felt for the weapons they had hidden around their persons.

"So you decided to come, Master Dongfang," Chen called from a nearby boat. "Please come aboard!"

The two boats drew alongside each and Qian Long, Commander Li, Bai, and several other bodyguards jumped across. Bai and the others relaxed as they saw that Chen and his attendant, Xin Yan, were the only other people on the boat. The cabin was spacious, with exquisite murals on the walls. The table in the centre was set with wine cups, bowls and chopsticks and was covered with dishes of fruit, wine and all manner of delicacies.

Chen and his guest shook hands and smiled broadly, then sat down facing each other. Commander Li, Bai and the others stood behind Qian Long.

Chen smiled briefly at Bai and noticed a handsome-faced youth standing behind Commander Li whom he recognised as Lu Feiqing's pupil. Surprised, he wondered what the youth was doing accompanying court officials.

Xin Yan poured some wine, and Chen, afraid that Qian Long would be suspicious, drained his own cup first, then began eating. Qian Long picked at a few of the dishes that Chen had already tried, then put down his chopsticks. He heard a flute on a neighbouring boat playing the tune 'Welcome the Honoured Guest.'

"You are truly a man of culture," he said to Chen. "It is amazing that you managed to arrange things so well at such short notice."

Chen dismissed the praise. "One cannot drink wine without music," he said. "I understand Beautiful Jade has the best voice in all Zhejiang Province. Shall I ask her to sing for us?"

Qian Long clapped his hands in approval. "Who is this Beautiful Jade?" he asked, turning to Commander Li.

"She is one of Hangzhou 's most famous courtezans," he replied. "I have heard that she is very haughty by nature and if it does not please her, she won't even show herself let alone sing, no matter how much she is offered."

"Have you ever seen her?" Qian Long asked.

"I…no I haven't," Li replied, extremely embarrassed.

'Leopard' Wei escorted Beautiful Jade out. Qian Long looked admiringly at the perfect whiteness of her skin and her petite figure, but decided her face was not particularly attractive. Her eyes, however, were full of life, and her glance around the cabin contained an intimate greeting for every person there.

Chen stretched out his hand towards Qian Long. "This is Master Dongfang," he said. Beautiful Jade greeted him, then sat down next to Chen and cuddled up to him.

"I hear you sing very well," Chen said. "I wonder if you would allow us the pleasure of enjoying your talent?"

"If you want to hear me sing, Master Lu, I will sing for three days and three nights continuously. But I am afraid you would tire of me." An attendant handed her a pipa, and with a light strum, she began to sing:

"Outside the window all is quiet

You kneel before the bed eager for some kissing

I scold you, call you heartless, and turn away,

But despite my words I am still half willing."

Chen applauded enthusiastically. Qian Long, hearing her smooth, clear voice, felt a warm feeling rising in his chest. Beautiful Jade smiled, then strummed the pipa and turned to Qian Long:

"I want to beat you,

Don't think I'm joking," she sang.

"I clench my teeth

This time I really will

But you won't fear me

If I hit you softly,

And I cannot bear

To hit you hard.

Oh, my lover

I won't hit you after all."

The Emperor was completely carried away by the song. "If you want to hit me, then hit me," he said.

Qian Long, born and raised in the depths of the Imperial Palace had seen many girl singers, but all of them had been dignified and monotonous, nothing like this southern Chinese courtesan. He was entranced by her eyes and her seductiveness, and the song, the perfumed lake, the moon's reflection, all conspired to make the scene dreamlike, so that gradually he forgot that he was with renowned bandits.

Beautiful Jade poured some wine for Chen and Qian Long and the two drank three cups in succession while Beautiful Jade drank one to keep them company. Qian Long took a jade ring off his finger and gave it to her.

"Sing another song," he said. Beautiful Jade looked down and giggled, revealing two little dimples. Qian Long's heart melted.

"All right," she said. She batted her eyelids at him then struck up a tune on the pipa. This time, the rhythm was fast and light with a complex melody, and Qian Long shouted out his approval.

She sang of a poor man with ambitions who gradually climbs his way up, first obtaining clothes, then a house, a wife and concubines, and then power. Finally, he begins to covet the throne of the emperor himself.

Chen laughed heartily, but as the song progressed, Qian Long's expression became increasingly dour. "Could this girl know who I really am and be singing this song to make fun of me?" he wondered.

Beautiful Jade finished the song and slowly put down her pipa.

"The song makes fun of poor men," she said with a smile. "Both of you, Master Dongfang and Master Chen, are wealthy gentlemen with large mansions, lovely wives and beautiful concubines. You would not think of such things."

Qian Long laughed, and his eyes travelled over her, taking in her softness, her fun-loving spirit. He wondered how he should go about telling Commander Li to have her brought to the Yamen, and how to make sure the affair remained secret.

"The Emperor Xuanzong had a great interest in beautiful women," he suddenly heard Chen say. "That in itself is not important, but he should not have put his weakness for women above the interests of the nation."

"The Xuanzong Emperor was at first a wise ruler, but he became muddle-headed in his later years. He was far inferior to his ancestor, Emperor Taizhong," Qian Long replied.

"Taizong was certainly a very capable ruler," said Chen.

The two men Qian Long most venerated in all the world were Emperor Wu of the Han dynasty and Emperor Taizong of the Tang dynasty. Both had greatly expanded the empire, and their reputations had carried far beyond their borders. Ever since he had ascended the throne, Qian Long had worked single-mindedly to emulate them and had sent armies out on long expeditions to the Muslim border regions with the intention of carrying on their work.
