Thai traditional games: There are more than 1,200 types of Thai traditional games.  These games originated in the era of the Sukhothai Kingdom (1238-1438).  Hundreds of years later, during the reign of Rama VI, the games grew popular again among Thai children.  The original purpose of Thai traditional games was to form good relationships between adults and young people, and for entertainment, relaxation, and exercise.  In that period, children's games were played with songs and rules to make them more entertaining.  They are designed to allow players from a range of socioeconomic statuses, as most traditional Thai games utilized raw natural materials.  For example, sand, mud balls, khan kluay (The stem of the banana tree) were components of games.  This use of raw, widely available materials makes Thai traditional games easy to play.

Second Invasion of the Kazakh Khanate (1509): In the year 1509, Shaybani Khan proceeded against the Kazakhs.

In spite of his great power, Shaybani Khan had not force enough to withstand Qasim Khan.  At that period, the numbers of his army exceeded 20,000.  In winter time every one stayed in some place where there was fodder for the cattle.  In the middle of the winter, Shaybani Khan was engaged in plundering Kazakh territories, but he soon returned, his object being not to remain too far from his own country.  Shaybani Khan made his last expedition into Kazakh territory, but the strength of his horses and soldiers was quite exhausted; he himself remained in the district of Kuk Kashana, and having detached a force, whose horses had some strength left, sent them forward.  This party fell in with a few men, whom they despoiled and made prisoners.  One day this same party had halted for the sake of feeding their horses, when news came that Qasim Khan, "Qasim Beg" was close at hand.  This news alarmed them.  Buyun Pir Hasan, one of Qasim Khan's Amirs, having heard of the invasion of the Uzbeks, advanced against them with his own army; he spread the report that Qasim Khan was approaching and had let himself be seen in the distance.  The Uzbeks being fully persuaded that Qasim Khan was really upon them, abandoned all they had seized, even all they had brought with them and retreated, in the utmost disorder and confusion, to Shaybani Khan, bearing the news of Qasim Khan's approach.  Shaybani Khan at once ordered them to sound the drum of retreat, without paying attention to anything but getting away.  The Uzbek army retreated in disorder for the first time in their military career since the advent of Shaybani Khan and reached Samarkand at the end of the winter.  Shaybani Khan himself went on to Khorasan, where he spent the spring.
